AMD A8-7670K (Godavari) Launches with Steamroller

Subject: Processors | July 22, 2015 - 09:56 PM |
Tagged: amd, APU, Godavari, a8, a8-7670k

AMD's Godavari architecture is the last one based on Bulldozer, which will hold the company's product stack over until their Zen architecture arrives in 2016. The A10-7870K was added a month ago, with a 95W TDP at a MSRP of $137 USD. This involved a slight performance bump of +200 MHz at its base frequency, but a +100 MHz higher Turbo than its predecessor when under high load. More interesting, it does this at the same TDP and the same basic architecture.

Remember that these are AMD's benchmarks.

The refresh has been expanded to include the A8-7670K. Some sites have reported that this uses the Excavator architecture as seen in Carrizo, but this is not the case. It is based on Steamroller. This product has a base clock of 3.6 GHz with a Turbo of up to 3.9 GHz. This is a +300 MHz Base and +100 MHz Turbo increase over the previous A8-7650K. Again, this is with the same architecture and TDP. The GPU even received a bit of a bump, too. It is now clocked at 757 MHz versus the previous generation's 720 MHz with all else equal, as far as I can tell. This should lead to a 5.1% increase in GPU compute throughput.

The A8-7670K just recently launched for an MSRP of $117.99. This 20$ saving should place it in a nice position below the A10-7870K for mainstream users.

Stop me if you've heard this before; change your .exe and change your performance

Subject: Graphics Cards | July 20, 2015 - 02:00 PM |
Tagged: amd, linux, CS:GO

Thankfully it has been quite a while since we saw GPU driver optimization specific to .exe filenames on Windows, in the past both major providers have tweaked performance based on the name of the executable which launches the game.  Until now this particular flavour of underhandedness had become passé, at least until now.  Phoronix has spotted it once again, this time seeing a big jump in performance in CS:GO when they rename the binary from csgo_linux binary to hl2_Linux.  The game is built on the same engine but the optimization for the Source Engine are not properly applied to CS:GO.

There is nothing nefarious about this particular example, it seems more a case of AMD's driver team being lazy, or more likely short-staffed.  If you play CS:GO on Linux then rename your binary, you will see a jump in performance with no deleterious side effects.  Phoronix is investigating more games to see if there are other inconsistently applied optimizations.

"Should you be using a Radeon graphics card with the AMD Catalyst Linux driver and are disappointed by the poor performance, there is a very easy workaround for gaining much better performance under Linux... In some cases a simple tweak will yield around 40% better performance!"

AMD's hopes for the second half of 2015

Subject: General Tech | July 20, 2015 - 01:16 PM |
Tagged: amd, lisa su

It has not been a pretty year for AMD with overall sales of $942m representing 34.6% drop from this time last year and even the graphics portion seeing a 54.2% drop which resulted in loss of $147 million.  In part this is because all PC component companies have been suffering recently; in part because of a lack of incentive to upgrade high end components and to a larger extent because the general public is not going to pick up a new machine just before the release of a new Windows version.  Lisa Su did have some good news, sales of FX processors and A-series APU have been increasing and the second half of the year is historically better for sales.  It was suggested to The Register that AMD is not currently planning on reducing their workforce even more at this time but the possibility of future cuts was not completely ruled out.

"AMD has confirmed it is slipping back into cost-cutting mode after its annus horribilis, caused by tanking demand for consumer PCs in a quarter described by CEO Lisa Su as the “revenue trough” for 2015."

TSMC Plans 10nm, 7nm, and "Very Steep" Ramping of 16nm.

Subject: Graphics Cards, Processors, Mobile | July 19, 2015 - 06:59 AM |

Getting smaller features allows a chip designer to create products that are faster, cheaper, and consume less power. Years ago, most of them had their own production facilities but that is getting rare. IBM has just finished selling its manufacturing off to GlobalFoundries, which was spun out of AMD when it divested from fabrication in 2009. Texas Instruments, on the other hand, decided that they would continue manufacturing but get out of the chip design business. Intel and Samsung are arguably the last two players with a strong commitment to both sides of the “let's make a chip” coin.

So where do you these chip designers go? TSMC is the name that comes up most. Any given discrete GPU in the last several years has probably been produced there, along with several CPUs and SoCs from a variety of fabless semiconductor companies.

Several years ago, when the GeForce 600-series launched, TSMC's 28nm line led to shortages, which led to GPUs remaining out of stock for quite some time. Since then, 28nm has been the stable work horse for countless high-performance products. Recent chips have been huge, physically, thanks to how mature the process has become granting fewer defects. The designers are anxious to get on smaller processes, though.

In a conference call at 2 AM (EDT) on Thursday, which is 2 PM in Taiwan, Mark Liu of TSMC announced that “the ramping of our 16 nanometer will be very steep, even steeper than our 20nm”. By that, they mean this year. Hopefully this translates to production that could be used for GPUs and CPUs early, as AMD needs it to launch their Zen CPU architecture in 2016, as early in that year as possible. Graphics cards have also been on that technology for over three years. It's time.

Also interesting is how TSMC believes that they can hit 10nm by the end of 2016. If so, this might put them ahead of Intel. That said, Intel was also confident that they could reach 10nm by the end of 2016, right until they announced Kaby Lake a few days ago. We will need to see if it pans out. If it does, competitors could actually beat Intel to the market at that feature size -- although that could end up being mobile SoCs and other integrated circuits that are uninteresting for the PC market.

Following the announcement from IBM Research, 7nm was also mentioned in TSMC's call. Apparently they expect to start qualifying in Q1 2017. That does not provide an estimate for production but, if their 10nm schedule is both accurate and also representative of 7nm, that would production somewhere in 2018. Note that I just speculated on an if of an if of a speculation, so take that with a mine of salt. There is probably a very good reason that this date wasn't mentioned in the call.

Back to the 16nm discussion, what are you hoping for most? New GPUs from NVIDIA, new GPUs from AMD, a new generation of mobile SoCs, or the launch of AMD's new CPU architecture? This should make for a highly entertaining comments section on a Sunday morning, don't you agree?

AMD Confirms August Availability of Radeon R9 Nano

Tagged: radeon, r9 nano, hbm, Fiji, amd

AMD has spilled the beans on at least one aspect of the R9 Nano: the release timeframe. On their Q2 earnings call yesterday AMD CEO Lisa Su made this telling remark:

“Fury just launched, actually this week, and we will be launching Nano in the August timeframe.”

Wccftech had the story based on the AMD earnings call, but unfortunately there is no other new information the card just yet. We've speculated on how much lower clocks would need to be to meet the 175W target with full Fiji silicon, and it's going to be significant. The air coolers we've seen on the Fury (non-X) cards to date have extended well beyond the PCB, and the Nano is a mini-ITX form factor design.

Regardless of where the final GPU and memory clock numbers are I think it's safe to assume there won't be much (if any) overclocking headroom. Then again, of the card does have higher performance than the 290X in a mini ITX package at 175W, I don't think OC headroom will be a drawback. I guess we'll have to keep waiting for more information on the official specs before the end of August.

Meet ASUS' DirectCU III on the Radeon Fury

Subject: Graphics Cards | July 13, 2015 - 03:34 PM |
Tagged: Fury, DirectCU III, asus, amd

The popular ASUS STRIX series has recently been updated with the DirectCU III custom cooler, on both the GTX 980 and the new Radeon Fury.  This version uses dual-10mm heatpipes and Triple Wing-Blade fans which are billed as providing 220% larger surface area as well as an increase in air pressure of 105%, which provide a claimed 40% reduction in temperature.  We cannot directly compare the cooling ability directly to the retail model, however [H]ard|OCP's tests show you can indeed cool a Fury on air, 71C at full load is lower than the 81C seen on a GTX 980.  Even more impressive is that fans were only at 43% speed and operating almost silently, at the cost of increased noise you could lower those temperatures if you desired.  Check out their full review to see how the card did but do take note, [H] does not at this time have access to the new GPU Tweak II utility required to overclock the card.

-update - now with less X's

"AMD's Radeon Fury X is here, the AMD Radeon R9 Fury presents itself and we evaluate a full retail custom ASUS STRIX R9 Fury using ASUS' new DirectCU III technology. We will compare this to a GeForce GTX 980 using the new drivers AMD just released and find out what kind of gameplay experience the R9 Fury has to offer."

Fiji brings the (non-X) Fury

Last month was a big one for AMD. At E3 the company hosted its own press conference to announce the Radeon R9 300-series of graphics as well as the new family of products based on the Fiji GPU. It started with the Fury X, a flagship $650 graphics card with an integrated water cooler that was well received.  It wasn't perfect by any means, but it was a necessary move for AMD to compete with NVIDIA on the high end of the discrete graphics market.

At the event AMD also talked about the Radeon R9 Fury (without the X) as the version of Fiji that would be taken by board partners to add custom coolers and even PCB designs. (They also talked about the R9 Nano and a dual-GPU version of Fiji, but nothing new is available on those products yet.) The Fury, priced $100 lower than the Fury X at $549, is going back to a more classic GPU design. There is no "reference" product though, so cooler and PCB designs are going to vary from card to card. We already have two different cards in our hands that differ dramatically from one another.

The Fury cuts down the Fiji GPU a bit with fewer stream processors and texture units, but keeps most other specs the same. This includes the 4GB of HBM (high bandwidth memory), 64 ROP count and even the TDP / board power. Performance is great and it creates an interesting comparison between itself and the GeForce GTX 980 cards on the market. Let's dive into this review!

SLI and CrossFire

Last week I sat down with a set of three AMD Radeon R9 Fury X cards, our sampled review card as well as two retail cards purchased from Newegg, to see how the reports of the pump whine noise from the cards was shaping up. I'm not going to dive into that debate again here in this story as I think we have covered it pretty well thus far in that story as well as on our various podcasts, but rest assured we are continuing to look into the revisions of the Fury X to see if AMD and Cooler Master were actually able to fix the issue.

group1.jpg

What we have to cover today is something very different, and likely much more interesting for a wider range of users. When you have three AMD Fury X cards in your hands, you of course have to do some multi-GPU testing with them. With our set I was able to run both 2-Way and 3-Way CrossFire with the new AMD flagship card and compare them directly to the comparable NVIDIA offering, the GeForce GTX 980 Ti.

There isn't much else I need to do to build up this story, is there? If you are curious how well the new AMD Fury X scales in CrossFire with two and even three GPUs, this is where you'll find your answers.
