According to AnarchX on the Beyond3D forums, a senior engineer at AMD has posted about a project he's working on - which just so happens to be the Polaris GPU from AMD.
The engineer notes that the die size of Polaris will be 232mm² which is just one tier of the Polaris pie. Now remember, Polaris is being made on the 14nm process - so if we compare it to a 28nm part, it would be a 464mm² die - at the same TDP levels.
We know that AMD wants to increase performance but keep the power numbers low, so we should be expecting some huge improvements in performance, without much more pressure being applied to power numbers.
But then we have to remember the tweets from RTG boss Raja Koduri, who said before the Polaris unveiling in Sonoma that "Polaris is 2.5 times brighter today than when Ptolemy observed it in 169 A.D". If Koduri was talking about 2.5x performance, then we're looking at the 232mm² GPU being compared against a 28nm 580mm² - with the same power levels - which would be insane.
We don't know when to expect the Radeon R9 Fury X2 aka Gemini from AMD, as it was promised for late last year - but the dual-GPU from AMD has been teased once again, from recent AMD recruit and all round cool guy Scott Wasson.
Scott posted an image of two Fiji GPUs on his Twitter account, without saying anything else. It's very similar to the marketing campaign for the Radeon R9 295X2, which saw reviewers teasing with the hashtag #2BETTERTHAN1 after AMD had sent them boxes of volcanic water and two cans of chips.
We should expect AMD to show off the Radeon R9 Fury X2 at GDC next month, well - that's what I'm expecting, anyway.
As the weeks fly past, we're getting closer and closer to the reveal of the next-gen GPUs from both NVIDIA and AMD. Today, we have news that NVIDIA is currently testing four of its next-gen Pascal-based GPUs.
The four Pascal GPUs have reached the testing and validation phase, with the GPUs being sent from TSMC's fabrication plants to NVIDIA's testing facilities in India. The four boards include the '699' serial number which was spotted back in December, with these four cards having the following serial numbers:
Now, this might not seem like much but the last card with '12914' in its serial number is very different. The first three look like iteration changes between them, while the 12914 board is very different - let's hope that this is the HBM2-powered successor to the GeForce GTX Titan X - something that should be unveiled at NVIDIA's GPU Technology Conference in early April.
Micron has updated us on the status of GDDR5X, with the company receiving their first samples back from their fabrication plant, earlier than expected.
These samples are 100% operational at data rates passing 13Gbps, with the company still testing its GDDR5X production line, with GDDR5X samples being sent to partners in the spring (over the next few months). Right now, the 13Gbps-capable GDDR5X chips don't consume any more power than the current GDDR5 chips, so in certain scenarios, GDDR5X-based cards will actually use less power, when maximum VRAM bandwidth isn't required.
GDDR5 has an 8Gbps data rate, so the huge 13Gbps that GDDR5X has hit before it's even in volume production is a huge achievement by Micron. The company is hoping to reach 14Gbps, but hasn't said when this will happen. Micron explained on their blog: "Compared to GDDR5, these ultra-high data rates were achieved at an improved power consumption per transmitted bit due to VDD/VDDQ of 1.35V, while not gating maximum speed of the device. We also added features to improve system signal integrity: a new package with reduced ball pitch enables shorter PCB traces, which improves electrical performance".
While the Super Bowl 50 continues, we're seeing that AMD has been pushing its next-gen Polaris GPUs around - with a new Polaris-based flagship GPU, and the successor to the Fury X making an appearance.
The new C99 "FOC" (Full Operational Capacity) has been spotted on Zauba, with the C99 part being priced at $1700. This is an insane jump from the price of the previous Polaris-based C98 and C91/C92 chips. The C98 should be the successor to the R9 390 series, which will arrive as the new Polaris-based R9 490/490X. The C99 on the other hand could be the huge enthusiast Polaris, the successor to the Fury X, or some crazy dual-GPU beast.
The C98 board turned up on Zauba last month, and it holds a per unit value that is more than AMD's current Hawaii-based chips. The C91/C92 chips started shipping in January of last year, but the FOC designation was only attached in August 2015. The C91/C92 should be the lower-end Polaris-bases GPUs, which would most likely be the cards we were greeted to in Sonoma in December, and officially unveiled early January.
As promised, and a little quicker than expected perhaps, AMD's updated 16.1.1 driver has been released. This one includes all the fixes from yesterday, as well as a new one for flickering in Fallout 4, as seen post-version 1.3 and with Crossfire enabled.
If you missed the news yesterday, the driver includes Crossfire profiles for Rise of the Tomb Raider and Fallout 4, plus resolved issues for Radeon Settings and three high profile games (Battlefront, Assasin's Creed Syndicate, Battlefield Hardline). For all the details and the download, click here.
AMD's 16.1.1 hotfix driver brought Crossfire improvements to Fallout 4 when it arrived yesterday. Then Bethesda released a patch for the game which introduced a Crossfire compatibility issue, and so AMD is releasing a second hotfix driver.
The company's software strategy manager Terry Makedon says it will arrive sometime today. Naturally, we'll let you know when it's available.
Now that Rise of the Tomb Raider is out, people are finding out just how useless their second GPUs are - except now, someone has found a fix for SLI users with multiple NVIDIA GeForce video cards.
3D Center's "Blaire" found some things to play around with in the NVIDIA Inspector Tool for SLI, which enables awesome SLI results. In order to do it, you'll need to search for Rise of the Tomb Raider's profile, and then change the SLI bits (DX11) to 0x080002F5. After that, click the magnifier icon that will reveal NVIDIA's Undefined options, and search for 0x00A0694B and change it to 0x00000001.
After you've done this, you've enabled full SLI support for Rise of the Tomb Raider, with DSO Gaming reporting that they've noticed 95% scaling on their GeForce GTX 690 - a damn good result for SLI scaling.
AMD was all systems go at VRLA last week, but during the VRLA Winter Expo keynote, the company teased its dual-GPU... the Radeon R9 Fury X2.
AMD's Roy Taylor said that the Radeon R9 Fury X2 has around 12 TFLOPS of SP, compared to the Radeon R9 295X2 which has 11.5 TFLOPS of SP compute performance. The big difference between the Fiji-based R9 Fury X2 and the Hawaii-based R9 295X2 is that the Fury X2 uses only 375W of power, compared to the R9 295X2 which would chew 500W. This means that the Fury X2 is around 40% more power efficient than the R9 295X2.
During his speech, Taylor said: "Last time I was here I also promised you that we would make the world's most powerful small computer for developers. We promised you we would take two of our highest end GPUs and put it inside that tiny box and if you go downstairs we actually have a demonstration of a dual GPU, 12 TeraFlops, fastest GPU solution in the world, inside of Tiki. It's a feat of engineering we are delighted with".
PC port specialist Nixxes Software has posted a tech support guide to Rise of the Tomb Raider on the Steam forums, just a few hours ahead of the game's launch. In the process, they've made it known AMD will be releasing a 16.1.1 driver "shortly", which they (Nixxes) recommends installing for the game.
It's possible 16.1.1 will include optimizations specifically for the game as is usually the case for big launches; NVIDIA did just this yesterday.
Asked for comment, AMD said, "We're working towards a hotfix that will have improvements for TR, but it's a work in progress. We can't comment on the timing or the details, but we'll keep you posted!"
