NVIDIA Announces the GeForce RTX 20 Series: RTX 2080 Ti & 2080 on Sept. 20th, RTX 2070 in October

NVIDIA's Gamescom 2018 keynote just wrapped up, and as many have been expecting since it was announced last month, NVIDIA is getting ready to launch their next generation of GeForce hardware. Announced at the event and going on sale starting September 20th is NVIDIA's GeForce RTX 20 series, which is succeeding the current Pascal-powered GeForce GTX 10 series. Based on NVIDIA's new Turing GPU architecture and built on TSMC's 12nm "FFN" process, NVIDIA has lofty goals, looking to drive an entire paradigm shift in how games are rendered and how PC video cards are evaluated. CEO Jensen Huang has called Turing NVIDIA's most important GPU architecture since 2006's Tesla GPU architecture (G80 GPU), and from a features standpoint it's clear that he's not overstating matters.

[...] So what does Turing bring to the table? The marquee feature across the board is hybrid rendering, which combines ray tracing with traditional rasterization to exploit the strengths of both technologies. This announcement is essentially a continuation of NVIDIA's RTX announcement from earlier this year, so if you thought that announcement was a little sparse, well then here is the rest of the story.

The big change here is that NVIDIA is going to be including even more ray tracing hardware with Turing in order to offer faster and more efficient hardware ray tracing acceleration. New to the Turing architecture is what NVIDIA is calling an RT core, the underpinnings of which we aren't fully informed on at this time, but serve as dedicated ray tracing processors. These processor blocks accelerate both ray-triangle intersection checks and bounding volume hierarchy (BVH) manipulation, the latter being a very popular data structure for storing objects for ray tracing.

NVIDIA is stating that the fastest GeForce RTX part can cast 10 Billion (Giga) rays per second, which compared to the unaccelerated Pascal is a 25x improvement in ray tracing performance.

Nvidia has confirmed that the machine learning capabilities (tensor cores) of the GPU will used to smooth out problems with ray-tracing. Real-time AI denoising (4m17s) will be used to reduce the amount of samples per pixel needed to achieve photorealism.

The NVIDIA GeForce RTX 2060 6GB Founders Edition Review: Not Quite Mainstream

In the closing months of 2018, NVIDIA finally released the long-awaited successor to the Pascal-based GeForce GTX 10 series: the GeForce RTX 20 series of video cards. Built on their new Turing architecture, these GPUs were the biggest update to NVIDIA's GPU architecture in at least half a decade, leaving almost no part of NVIDIA's architecture untouched.

So far we've looked at the GeForce RTX 2080 Ti, RTX 2080, and RTX 2070 – and along with the highlights of Turing, we've seen that the GeForce RTX 20 series is designed on a hardware and software level to enable realtime raytracing and other new specialized features for games. While the RTX 2070 is traditionally the value-oriented enthusiast offering, NVIDIA's higher price tags this time around meant that even this part was $500 and not especially value-oriented. Instead, it would seem that the role of the enthusiast value offering is going to fall to the next member in line of the GeForce RTX 20 family. And that part is coming next week.

Launching next Tuesday, January 15th is the 4th member of the GeForce RTX family: the GeForce RTX 2060 (6GB). Based on a cut-down version of the same TU106 GPU that's in the RTX 2070, this new part shaves off some of RTX 2070's performance, but also a good deal of its price tag in the process

AMD, Nvidia Have Launched the Least-Appealing GPU Upgrades in History

Yesterday, AMD launched the Radeon VII, the first 7nm GPU. The card is intended to compete with Nvidia's RTX family of Turing-class GPUs, and it does, broadly matching the RTX 2080. It also matches the RTX 2080 on price, at $700. Because this card began life as a professional GPU intended for scientific computing and AI/ML workloads, it's unlikely that we'll see lower-end variants. That section of AMD's product stack will be filled by 7nm Navi, which arrives later this year.

Navi will be AMD's first new 7nm GPU architecture and will offer a chance to hit 'reset' on what has been, to date, the least compelling suite of GPU launches AMD and Nvidia have ever collectively kicked out the door. Nvidia has relentlessly moved its stack pricing higher while holding performance per dollar mostly constant. With the RTX 2060 and GTX 1070 Ti fairly evenly matched across a wide suite of games, the question of whether the RTX 2060 is better priced largely hinges on whether you stick to formal launch pricing for both cards or check historical data for actual price shifts.

Such comparisons are increasingly incidental, given that Pascal GPU prices are rising and cards are getting harder to find, but they aren't meaningless for people who either bought a Pascal GPU already or are willing to consider a used card. If you're an Nvidia fan already sitting on top of a high-end Pascal card, Turing doesn't offer you a great deal of performance improvement.

AMD has not covered itself in glory, either. The Radeon VII is, at least, unreservedly faster than the Vega 64. There's no equivalent last-generation GPU in AMD's stack to match it. But it also duplicates the Vega 64's overall power and noise profile, limiting the overall appeal, and it matches the RTX 2080's bad price. A 1.75x increase in price for a 1.32x increase in 4K performance isn't a great ratio even by the standards of ultra-high-end GPUs, where performance typically comes with a price penalty.

Rumors and leaks have suggested that Nvidia will release a Turing-based GPU called the GTX 1660 Ti (which has also been referred to as "1160"), with a lower price but missing the dedicated ray-tracing cores of the RTX 2000-series. AMD is expected to release "7nm" Navi GPUs sometime during 2019.

At Computex 2019 in Taipei, AMD CEO Lisa Su gave a keynote presentation announcing the first "7nm" Navi GPU and Ryzen 3000-series CPUs. All of the products will support PCI Express 4.0.

Contrary to recent reports, AMD says that the Navi microarchitecture is not based on Graphics Core Next (GCN), but rather a new "RDNA" macroarchitecture ('R' for Radeon), although the extent of the difference is not clear. There is also no conflict with Nvidia's naming scheme; the 5000-series naming is a reference to the company's 50th anniversary.

AMD claims that Navi GPUs will have 25% better performance/clock and 50% better performance/Watt vs. Vega GPUs. AMD Radeon RX 5700 is the first "7nm" Navi GPU to be announced. It was compared with Nvidia's GeForce RTX 2070, with the RX 5700 outperforming the RTX 2070 by 10% in the AMD-favorable game Strange Brigade. Pricing and other launch details will be revealed on June 10.

AMD also announced the first five Ryzen 3000-series CPUs, all of which will be released on July 7:

The Ryzen 9 3900X is the only CPU in the list using two core chiplets, each with 6 of 8 cores enabled. AMD has held back on releasing a 16-core monster for now. AMD compared the Ryzen 9 3900X to the $1,189 Intel Core i9-9920X, the Ryzen 7 3800X to the $499 Intel Core i9-9900K, and the Ryzen 7 3700X to the Intel Core i7-9700K, with the AMD chips outperforming the Intel chips in certain single and multi-threaded benchmarks (wait for the reviews before drawing any definitive conclusions). All five of the processors will come with a bundled cooler, as seen in this list.

At AMD's keynote at the 2019 Electronic Entertainment Expo (E3), AMD CEO Lisa Su announced three new "7nm" Navi GPUs and a new CPU.

The AMD Radeon RX 5700 XT will have 2560 stream processors (40 compute units) capable of 9.75 TFLOPs of FP32 performance, with 8 GB of 14 Gbps GDDR6 VRAM. The price is $449. The AMD RX 5700 cuts that down to 2304 SPs (36 CUs), 7.9 TFLOPs, at $379. There is a higher clocked "50th anniversary" version of the 5700 XT that offers up to 10.14 teraflops for $499. A teraflop on one of these new cards supposedly means better graphics performance than older Polaris-based GPUs:

Looking at these clockspeed values then, in terms of raw throughput the new card is expected to get between 9 TFLOPs and 9.75 TFLOPs of FP32 compute/shading throughput. This is a decent jump over the Polaris cards, but on the surface it doesn't look like a huge, generational jump, and this is where AMD's RDNA architecture comes in. AMD has made numerous optimizations to improve their GPU utilization – that is, how well they put those FLOPs to good use – so a teraflop on a 5700 card means more than it does on preceding AMD cards. Overall, AMD says that they're getting around 25% more work done per clock on the whole in gaming workloads. So raw specs can be deceiving.

The GPUs do not include real-time raytracing or variable rate pixel shading support. These may appear on a future generation of GPUs. Instead, AMD talked about support for DisplayPort 1.4 with Display Stream Compression, a contrast-enhancing post-processing filter, AMD Radeon Image Sharpening, and a Radeon Anti-lag feature to reduce input lag.

Towards the end of the presentation, AMD revealed the 16-core Ryzen 9 3950X, the company's fully-fledged Ryzen CPU with two 8-core "7nm" Zen 2 chiplets. Compared to the 12-core Ryzen 9 3900X CPU, the 3950X has a slightly higher boost clock and L2 cache, with the same 105 Watt TDP, for $749. This is the full lineup so far:

AMD cuts Radeon 5700 GPU prices just two days before their release

When AMD announced its next-gen Navi-based Radeon RX 5700 and 5700 XT graphics cards last month, the news was just slightly underwhelming because the prices didn't necessarily make them the obvious alternative to Nvidia's rival chips.

But just two days before their July 7th launch date, AMD has taken the drastic step of dropping the prices on these new GPUs.

The Radeon 5700 XT, previously listed at $450, will now cost $400, and the Radeon 5700, previously $380, will be priced at $350. (There's also a $500 Radeon RX 5700 XT 50th Anniversary Edition that'll retail for $450.)

That's just super.
