Joe Macri on Ryzen

Tagged: video, amd, Joe Macri, ryzen

TechARP just posted a video of AMD's Joe Macri discussing the new Ryzen processors from AMD.  It is not quite 20 minutes long which gives you a chance to quickly hear from AMD about what they feel the new architecture means for the company, as well as the impact it will have on gamers and enthusiasts.  He does mention the HSA Foundation and how AMD is working towards a basic change in how PCs utilize resources. They also embedded a link to a video featuring AMD's Radeon Product Marketing Manager, Adam Kozak, on the new 500 series if you have time.

Background and setup

A couple of weeks back, during the excitement surrounding the announcement of the GeForce GTX 1080 Ti graphics card, NVIDIA announced an update to its performance reporting project known as FCAT to support VR gaming. The updated iteration, FCAT VR as it is now called, gives us the first true ability to not only capture the performance of VR games and experiences, but the tools with which to measure and compare.

Watch ths video walk through of FCAT VR with me and NVIDIA's Tom Petersen

I already wrote an extensive preview of the tool and how it works during the announcement. I think it’s likely that many of you overlooked it with the noise from a new GPU, so I’m going to reproduce some of it here, with additions and updates. Everyone that attempts to understand the data we will be presenting in this story and all VR-based tests going forward should have a baseline understanding of the complexity of measuring VR games. Previous tools don’t tell the whole story, and even the part they do tell is often incomplete.

If you already know how FCAT VR works from reading the previous article, you can jump right to the beginning of our results here.

Measuring and validating those claims has proven to be a difficult task. Tools that we used in the era of standard PC gaming just don’t apply. Fraps is a well-known and well-understood tool for measuring frame rates and frame times utilized by countless reviewers and enthusiasts, but Fraps lacked the ability to tell the complete story of gaming performance and experience. NVIDIA introduced FCAT and we introduced Frame Rating back in 2013 to expand the capabilities that reviewers and consumers had access to. Using more sophisticated technique that includes direct capture of the graphics card output in uncompressed form, a software-based overlay applied to each frame being rendered, and post-process analyzation of that data, we could communicate the smoothness of a gaming experience, better articulating it to help gamers make purchasing decisions.

For VR though, those same tools just don’t cut it. Fraps is a non-starter as it measures frame rendering from the GPU point of view and completely misses the interaction between the graphics system and the VR runtime environment (OpenVR for Steam/Vive and OVR for Oculus). Because the rendering pipeline is drastically changed in the current VR integrations, what Fraps measures is completely different than the experience the user actually gets in the headset. Previous FCAT and Frame Rating methods were still viable but the tools and capture technology needed to be updated. The hardware capture products we used since 2013 were limited in their maximum bandwidth and the overlay software did not have the ability to “latch in” to VR-based games. Not only that but measuring frame drops, time warps, space warps and reprojections would be a significant hurdle without further development.

NVIDIA decided to undertake the task of rebuilding FCAT to work with VR. And while obviously the company is hoping that it will prove its claims of performance benefits for VR gaming, it should not be overlooked the investment in time and money spent on a project that is to be open sourced and free available to the media and the public.

vlcsnap-2017-02-27-11h31m17s057.png

NVIDIA FCAT VR is comprised of two different applications. The FCAT VR Capture tool runs on the PC being evaluated and has a similar appearance to other performance and timing capture utilities. It uses data from Oculus Event Tracing as a part of the Windows ETW and SteamVR’s performance API, along with NVIDIA driver stats when used on NVIDIA hardware to generate performance data. It will and does work perfectly well on any GPU vendor’s hardware though with the access to the VR vendor specific timing results.

Flagship Performance Gets Cheaper

UPDATE! If you missed our launch day live stream, you can find the reply below:

It’s a very interesting time in the world of PC gaming hardware. We just saw the release of AMD’s Ryzen processor platform that shook up the processor market for the first time in a decade, AMD’s Vega architecture has been given the brand name “Vega”, and the anticipation for the first high-end competitive part from AMD since Hawaii grows as well. AMD was seemingly able to take advantage of Intel’s slow innovation pace on the processor and it was hoping to do the same to NVIDIA on the GPU. NVIDIA’s product line has been dominant in the mid and high-end gaming market since the 900-series with the 10-series products further cementing the lead.

box1.jpg

The most recent high end graphics card release came in the form of the updated Titan X based on the Pascal architecture. That was WAY back in August of 2016 – a full seven months ago! Since then we have seen very little change at the top end of the product lines and what little change we did see came from board vendors adding in technology and variation on the GTX 10-series.

Today we see the release of the new GeForce GTX 1080 Ti, a card that offers only a handful of noteworthy technological changes but instead is able to shake up the market by instigating pricing adjustments to make the performance offers more appealing, and lowering the price of everything else.

The GTX 1080 Ti GP102 GPU

I already wrote about the specifications of the GPU in the GTX 1080 Ti when it was announced last week, so here’s a simple recap.

  GTX 1080 Ti Titan X (Pascal) GTX 1080 GTX 980 Ti TITAN X GTX 980 R9 Fury X R9 Fury R9 Nano

MSRP (current) $699 $1,200 $599 $649 $999 $499 $649 $549 $499

The GTX 1080 Ti looks a whole lot like the TITAN X launched in August of last year. Based on the 12B transistor GP102 chip, the new GTX 1080 Ti will have 3,584 CUDA core with a 1.60 GHz Boost clock. That gives it the same processor count as Titan X but with a slightly higher clock speed which should make the new GTX 1080 Ti slightly faster by at least a few percentage points and has a 4.7% edge in base clock compute capability. It has 28 SMs, 28 geometry units, 224 texture units.

GeForce_GTX_1080_Ti_Block_Diagram.png

Interestingly, the memory system on the GTX 1080 Ti gets adjusted – NVIDIA has disabled a single 32-bit memory controller to give the card a total of 352-bit wide bus and an odd-sounding 11GB memory capacity. The ROP count also drops to 88 units. Speaking of 11, the memory clock on the G5X implementation on GTX 1080 Ti will now run at 11 Gbps, a boost available to NVIDIA thanks to a chip revision from Micron and improvements to equalization and reverse signal distortion.

The move from 12GB of memory on the GP102-based Titan X to 11GB on the GTX 1080 Ti is an interesting move, and evokes memories of the GTX 970 fiasco where NVIDIA disabled a portion of that memory controller but left the memory that would have resided on it ON the board. At that point, what behaved as 3.5GB of memory at one speed and 500 MB at another speed, was the wrong move to make. But releasing the GTX 970 with "3.5GB" of memory would have seemed odd too. NVIDIA is not making the same mistake, instead building the GTX 1080 Ti with 11GB out the gate.
