NVIDIA GeForce RTX 2080 Ti PCI-Express Scaling

NVIDIA GeForce RTX 2080 Ti PCI-Express Scaling48(48 Comments) »

Conclusion

Our last PCI-Express scaling article was close to 20 months ago, with the GeForce GTX 1080 "Pascal," which we admit isn't exactly the predecessor of the RTX 2080 Ti, but was the fastest graphics card you could buy then. The GTX 1080 did not saturate PCI-Express 3.0 x16 by a long shot, and we observed no changes in performance between gen 3.0 x16 and gen 3.0 x8 at any resolution.

We are happy to report that the RTX 2080 Ti is finally able to overwhelm PCIe gen 3.0 x8, posting a small but tangible 2%–3% performance gain when going from gen 3.0 x8 to gen 3.0 x16, across resolutions. Granted, these are single-digit percentage differences, and you won't be able to notice them in regular gameplay, but graphics card makers expect you to pay like $100 premiums for factory overclocks that fetch essentially that much more performance out of the box. The performance difference isn't nothing, just like with those small out-of-the-box performance gains, but such small differences are impossible to notice in regular gameplay.

This should also mean PCI-Express 2.0 x16 (in case of people still clinging on to platforms like "Sandy Bridge-E" or AMD FX) can impose a (small) platform bottleneck with the RTX 2080 Ti. On top of that, the weaker CPU performance can also cause a bottleneck in some games, especially at high FPS rates.

The performance differences between PCIe bandwidth configurations are more pronounced at lower resolutions than 4K, which isn't new. We saw this in every previous PCI-Express scaling test. The underlying reason is that the framerate is the primary driver of PCIe bandwidth, not the resolution. Bus transfers are fairly constant for a given scene for each frame, independent of the resolution. The final rendered image never moves across the bus except in render engines that do post-processing on the CPU, which has gotten much more common since we last looked at PCIe scaling. Yet even so, the reduction in FPS due to a higher resolution is still bigger than the increase in pixel data.

Some titles seemingly show the opposite: all cards bunched up against a wall at 1080p, and the differences get bigger at higher resolution. These cases, like GTA V, are CPU limited at lower resolutions; i.e. the per-frame game logic (on the CPU) can't run any faster and is thus limiting the frame rate even though the GPU could run faster. When the resolution is higher, the FPS rate goes down, which takes some load off the CPU, moving the bottleneck to the GPU, which makes it possible for PCIe to become a bottleneck too.

The performance takes an even bigger hit as you lower bandwidth to PCIe gen 3.0 x4 (comparable to gen 2.0 x8), though still not by the double-digit percentages we were expecting to see. You lose 9% performance compared to gen 3.0 x16 at 1080p, 8% at 1440p, and, surprisingly, just 6% at 4K.

Don't take our PCIe gen 3.0 x4 numbers as a green light for running your RTX 2080 Ti in the bottom-most PCIe x16 slot on your motherboard, which tends to be x4 electrically. That slot is most likely wired to your motherboard chipset instead of the CPU. Using it for graphics cards would be saturating the chipset bus, the connection between the chipset and the CPU, which other bandwidth-heavy components in your machine rely on, such as network adapters and SATA SSDs, and all of these components share the bandwidth of that x4 link.

We also decided to test PCIe gen 2.0 x4 purely for academic reasons, just because we tested bus widths as low as x1 in the past. Don't try this at home. Performance drops like a rock across resolutions, by up to 22% at 1080p.

What do these numbers spell for you? For starters, installing the RTX 2080 Ti in the topmost x16 slot of your motherboard while sharing half its PCIe bandwidth with another device in the second slot, such as an M.2 PCIe SSD, will come with performance penalties, even if they're small. These penalties didn't exist with older-generation GPUs because those were slower and didn't need as much bandwidth. Again, you're looking at 3%, which may or may not be worth the convenience of being able to run another component; that's your decision.

For the first time since the introduction of PCIe gen 3.0 (circa 2011), 2-way SLI on a mainstream-desktop platform, such as Intel Z370 or AMD X470, could be slower than on an HEDT platform, such as Intel X299 or AMD X399, because mainstream-desktop platforms split one x16 link between two graphics cards, while HEDT platforms (not counting some cheaper Intel HEDT processors), provide uncompromising gen 3.0 x16 bandwidth for up to two graphics cards. Numbers for gen 3.0 x8 and gen 3.0 x4 also prove that PCI-Express gen 2.0 is finally outdated, so it's probably time you considered an upgrade for your 7-year old "Sandy Bridge-E" rig.

By this time next year, we could see the first desktop platforms and GPUs implementing PCI-Express gen 4.0 in the market. If only "Turing" supported PCIe gen 4.0, you would have had the luxury to run it at gen 4.0 x8 without worrying about any performance loss. Exactly this is the promise of PCIe gen 4.0, not more bandwidth per device, but each device working happily with a lower number of lanes, so processor makers aren't required to add more lanes.

GeForce 20 series

Series of GPUs by Nvidia

The GeForce 20 series is a family of graphics processing units developed by Nvidia.[4] Serving as the successor to the GeForce 10 series,[5] the line started shipping on September 20, 2018,[6] and after several editions, on July 2, 2019, the GeForce RTX Super line of cards was announced.[7]

The 20 series marked the introduction of Nvidia's Turing microarchitecture, and the first generation of RTX cards,[8] the first in the industry to implement realtimehardwareray tracing in a consumer product.[9] In a departure from Nvidia's usual strategy, the 20 series doesn't have an entry level range, leaving it to the 16 series to cover this segment of the market.[10]

These cards are succeeded by the GeForce 30 series, powered by the Ampere microarchitecture.[11]

History[edit]

Announcement[edit]

On August 14, 2018, Nvidia teased the announcement of the first card in the 20 series, the GeForce RTX 2080, shortly after introducing the Turing architecture at SIGGRAPH earlier that year.[8] The GeForce 20 series was finally announced at Gamescom on August 20, 2018,[4] becoming the first line of graphics cards "designed to handle real-time ray tracing" thanks to the "inclusion of dedicated tensor and RT cores."[9]

In August 2018, it was reported that Nvidia had trademarked GeForce RTX and Quadro RTX as names.[12]

Release[edit]

The line started shipping on September 20, 2018.[6] Serving as the successor to the GeForce 10 series,[5] the 20 series marked the introduction of Nvidia's Turing microarchitecture, and the first generation of RTX cards, the first in the industry to implement realtimehardwareray tracing in a consumer product.[citation needed]

Released in late 2018, the RTX 2080 was marketed as up to 75% faster than the GTX 1080 in various games,[13] also describing the chip as "the most significant generational upgrade to its GPUs since the first CUDA cores in 2006," according to PC Gamer.[14]

After the initial release, factory overclocked versions were released in the fall of 2018.[15] The first was the "Ti" edition,[16] while the Founders Edition cards were overclocked by default and had a three-year warranty.[13] When the GeForce RTX 2080 Ti came out, TechRadar called it "the world’s most powerful GPU on the market."[17] The GeForce RTX 2080 Founders Edition was positively reviewed for performance by PC Gamer on September 19, 2018,[18] but was criticized for the high cost to consumers,[18][19] also noting that its ray tracing feature wasn't yet utilized by many programs or games.[18] In January 2019, Tom's Hardware also stated the GeForce RTX 2080 Ti Xtreme was "the fastest gaming graphics card available," although it criticized the loudness of the cooling solution, the size and heat output in PC cases.[20] In August 2018, the company claimed that the GeForce RTX graphics cards were the "world’s first graphics cards to feature super-fast GDDR6 memory, a new DisplayPort 1.4 output that can drive up to 8K HDR at 60Hz on future-generation monitors with just a single cable, and a USB Type-C output for next-generation Virtual Reality headsets."[21]

In October 2018, PC Gamer reported the supply of the 2080 Ti card was "extremely tight" after availability had already been delayed.[22] By November 2018, MSI was offering nine different RTX 2080-based graphics cards.[23] Released in December 2018, the line's Titan RTX was initially priced at $2500, significantly more than the $1300 then needed for a GeForce RTX 2080 Ti.[24]

Marketing[edit]

In January 2019, Nvidia announced that GeForce RTX graphics cards would be used in 40 new laptops from various companies.[25] Also that month, in response to negative reactions to the pricing of the GeForce RTX cards, Nvidia CEO Jensen Huang stated "They were right. [We] were anxious to get RTX in the mainstream market... We just weren’t ready. Now we’re ready, and it’s called 2060," in reference to the RTX 2060.[26] In May 2019, a TechSpot review noted that the newly released Radeon VII by AMD was comparable in speeds to the GeForce RTX 2080, if slightly slower in games, with both priced similarly and framed as direct competitors.[27]

On July 2, 2019, the GeForce RTX Super line of cards was announced, which comprises higher-spec versions of the 2060, 2070 and 2080. Each of the Super models were offered for a similar price as older models but with improved specs.[7] In July 2019, NVidia stated the "SUPER" graphics cards in the GeForce RTX 20 series, to be introduced, had a 15% performance advantage over the GeForce RTX 2060.[28]PC World called the super editions a "modest" upgrade for the price, and the 2080 Super chip the "second most-powerful GPU ever released" in terms of speed.[29] In November 2019, PC Gamer wrote "even without an overclock, the 2080 Ti is the best graphics card for gaming."[30] In June 2020, PC Mag listed the Nvidia GeForce RTX 2070 Super as one of the "best [8] graphics cards for 4k gaming in 2020." The GeForce RTX 2080 Founders Edition, Super, and Ti were also listed.[31] In June 2020, graphic cards including the RTX 2060, RTX 2060 Super, RTX 2070 and the RTX 2080 Super were announced as discounted by retailers in expectation of the GeForce RTX 3080 launch.[32] In April 2020, Nvidia announced 100 new laptops licensed to include either GeForce GTX and RTX models.[33]

Reintroduction of older cards[edit]

Due to production problems surrounding the RTX 30-series cards and a general shortage of graphics cards due to production issues caused by the ongoing COVID-19 pandemic, which led to a global shortage of semiconductor chips, and general demand for graphics cards increasing due to an increase in cryptocurrency mining, the RTX 2060 and its Super counterpart, alongside the GTX 1050 Ti,[34] were brought back into production in 2021.[35][36]

Architecture[edit]

See also: Turing (microarchitecture) and Ray-tracing hardware

The RTX 20 series is based on the Turing microarchitecture and features real-time hardware ray tracing.[37] The cards are manufactured on an optimized 14 nm node from TSMC, named 12 nm FinFET NVIDIA (FFN).[38] New example features in Turing included mesh shaders,[39] rRay tracing (RT) cores (bounding volume hierarchy acceleration),[40] tensor (AI) cores,[9] dedicated Integer (INT) cores for concurrent execution of integer, and floating point operations.[41] In the GeForce 20 series, this real-time ray tracing is accelerated by the use of new RT cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual triangles.[citation needed]

The ray tracing performed by the RT cores can be used to produce effects such as reflections, refractions, shadows, depth of field, light scattering and caustics, replacing traditional raster techniques such as cube maps and depth maps.[citation needed] Notes: Instead of replacing rasterization entirely, however, ray tracing is offered in a hybrid model, in which the information gathered from ray tracing can be used to augment the rasterized shading for more photo-realistic results.[citation needed]

The second generation Tensor Cores (succeeding Volta's) work in cooperation with the RT cores, and their AI features are used mainly to two ends: firstly, de-noising a partially ray traced image by filling in the blanks between rays cast; also another application of the Tensor cores is DLSS (deep learning super-sampling), a new method to replace anti-aliasing, by artificially generating detail to upscale the rendered image into a higher resolution.[42] The Tensor cores apply deep learning models (for example, an image resolution enhancement model) which are constructed using supercomputers. The problem to be solved is analyzed on the supercomputer, which is taught by example what results are desired. The supercomputer then outputs a model which is then executed on the consumer's Tensor cores. These methods are delivered to consumers as part of the cards' drivers.[citation needed]

Nvidia segregates the GPU dies for Turing into A and non-A variants, which is appended or excluded on the hundreds part of the GPU code name. Non-A variants are not allowed to be factory overclocked, whilst A variants are.[43]

The GeForce 20 series was launched with GDDR6 memory chips from Micron Technology. However, due to reported faults with launch models, Nvidia switched to using GDDR6 memory chips from Samsung Electronics by November 2018.[44]

Software[edit]

Main article: Nvidia RTX

With the GeForce 20 series, Nvidia introduced the RTX development platform. RTX uses Microsoft's DXR, Nvidia's OptiX, and Vulkan for access to ray tracing.[45] The ray tracing technology used in the RTX Turing GPUs was in development at Nvidia for 10 years.[46] Nvidia's Nsight Visual Studio Edition application is used to inspect the state of the GPUs.[47]

Chipset table[edit]

All of the cards in the series are PCIe 3.0 x16 cards, manufactured using a 12 nmFinFET process from TSMC, and use GDDR6 memory (initially Micron chips upon launch, and later Samsung chips from November 2018).[44]

NVIDIA GeForce RTX 2080 Ti PCI-Express Scaling

Introduction

NVIDIA Logo

NVIDIA recently launched its GeForce RTX 20-series graphics cards based on its new "Turing" architecture with two high-end parts: the GeForce RTX 2080 Ti and RTX 2080. Despite a long list of innovations, NVIDIA chose to give these chips a PCI-Express 3.0 x16 bus interface, even though the PCI-Express gen 4.0 specification has been published over a year ago and could be implemented in desktop platforms in the next few months. Rival AMD is rumored to be implementing PCI-Express gen 4.0 in its next-generation GPU.

The PCI-Express bus interface has endured close to two decades of market dominance thanks to its scalable design, backwards compatibility, and near-doubling in data bandwidth every five years or so. PCI-Express generation 3, introduced in 2011, has seen NVIDIA and AMD launch four generations of GPUs on it, with each failing to saturate it at full x16 bus width. That, coupled with the decline in multi-GPU beyond two graphics cards, has blunted the overall connectivity edge the high-end desktop (HEDT) platform had over mainstream-desktop.



We have a tradition of testing PCI-Express bus utilization and scaling each time a new graphics architecture from either company is launched. We do so by testing a new generation graphics card's performance on various configurations of the PCI-Express bus by narrowing its bus width (number of lanes) and limiting its bandwidth to that of older generations, giving us valuable data to draw inferences on a number of things. It lets us know if the new GeForce RTX 2080 Ti can be bottlenecked in multi-GPU setups on mainstream desktop platforms and whether it's time you changed your old motherboard that uses older generations of PCI-Express. It will also help answer questions like "Will my graphics card run slower when using PCIe x8?" and "Do I need to run my SLI in x16, buying the more expensive X299 platform, for the best performance?"



In this review, we are taking the fastest graphics card from NVIDIA, the GeForce RTX 2080 Ti Founders Edition, and test it across PCI-Express 3.0 x16 (the most common configuration for single-GPU builds), PCI-Express 3.0 x8 (bandwidth comparable to PCI-Express 2.0 x16), PCI-Express 3.0 x4 (comparable to PCI-Express 2.0 x8), and for purely academic reasons, PCI-Express 2.0 x4 (what would happen if you installed your card in the bottom-most slot of your motherboard). The table below gives you an idea of the theoretical maximum bandwidths of the common PCI-Express configurations:



For all our PCI-Express bandwidth testing, we limit the bus-width by physically blocking the slot wiring for lanes using insulating tape. The modular design of PCI-Express allows for this. The motherboard BIOS lets us limit the PCI-Express feature set to that of older generations, too. We put the card in its various PCI-Express configurations through our entire battery of graphics card benchmarks, all of which are real-world game tests.
