This year’s AMD CES was actually more interesting than I was expecting. The details of the event were well known, as most Kaveri details have been revealed over the past few months. I was unsure what Lisa Su and the gang would go over, but it was actually more interesting than I was expecting.
This past year has been a big one for AMD. They seem to be doing a lot better than others expected them to, especially with all of the delayed product launches on the CPU side for quite a few years. This year saw the APU take a pretty prominent place in the industry with the launch of the latest generation consoles from Sony and Microsoft. AMD made inroads with mobile form factors with a variety of APUs. The HSA Foundation members have grown and HSA members ship two out of every three connected, smart devices. Apple also includes Firepro graphics cards with all of their new Mac Pros.
Kaveri is of course the big news here. AMD feels that this is the best APU yet. The combination of Steamroller CPU cores, GCN graphics compute cores, HSA, hUMA, HQ, TrueAudio, Mantle support, PCI-E 3.0 support, and a configurable TDP makes for a pretty compelling product. AMD has shuffled some nomenclature about by saying that Kaveri, at the top end, is comprised of 12 compute cores. These include 4 Steamroller cores and 8 GCN compute clusters. Each compute cluster matches the historical definition of a core, but of course it looks quite a bit different than a traditional x86 core.
We have gone over Kaveri pretty extensively in the past. The CPU is clocked at 3.7 GHz with a 4 GHz boost. The graphics portion clocks in at 720 MHz. It can support up to DDR-3 2400 MHz memory, which is really needed to extract as much performance out of this new APU. Benchmarks provided by AMD show this product to be a big jump from the previous Richland, and in these particular benchmarks are quite a bit faster than the competing i5 4670K.
Gaming performance is also improved. This APU can run most current applications at 1080P resolutions with low to medium quality settings. Older titles can be run at 1080P with Medium to High/Extreme settings. While this processor is rated at around 867 GFLOPS, which is around 110 GFLOPS greater than the previous top end Richland, it is more efficient at delivering that theoretical performance. It looks to be a significant improvement all around.
Software support is improving with applications from companies like Adobe, The Document Foundation, and Nuance. These cover HSA applications and in Nuance’s case, using the TrueAudio portion to clean up and accelerate voice recognition. TrueAudio is also being supported in five upcoming games. This is not a huge amount, but it is a decent start for this new technology.
Mantle is gaining a lot more momentum with support from 3 engines, 5 developers, and 20+ games in development. They showed off Battlefied 4 running Mantle on a Kaveri APU for the first time publicly. They mentioned that it ran 45% faster than Direct3D at the same quality levels on the same hardware. The display showed frame rates up in the low 50 fps area.
AMD is continuing to move forward on their low power offerings based on Beema and Mullins. Lisa claims that these parts are outperforming the Intel Baytrail offerings in both CPU performance and graphics. Unfortunately, she mentioned noting about the power consumption associated with these results. They showed off the Discovery tablet as well as a fully functional PC that was the size of a large cellphone.
They closed up the even by talking about the Surround House 2. This demo looks significantly better than the previous iteration we saw last year. This features something like a 34.2 speaker setup in a projected dome. It is much more complex than the House from last year, but the hardware running it all is rather common. A single high end Firepro card running on a single A10 7850K. The demo is also one of the first shows of a 360 degree gesture recognition setup.
AMD has come a long way since hitting rock bottom a few years back. They continue to claw their way back to relevance, and they hope that Kaveri will help them regain a foothold in the computing market. They are certainly doing well in the graphics market, but the introduction of Kaveri should help them gain more momentum in the CPU/APU market. We have yet to test Kaveri on our own, but initial results look promising. It is a better APU, but we just don’t know how much better so far.

Sapphire Triple Fan Hawaii
It was mid-December when the very first custom cooled AMD Radeon R9 290X card hit our offices in the form of the ASUS R9 290X DirectCU II. It was cooler, quieter, and faster than the reference model; this is a combination that is hard to pass up (if you could buy it yet). More and more of these custom models, both in the R9 290 and R9 290X flavor, are filtering their way into PC Perspective. Next on the chopping block is the Sapphire Tri-X model of the R9 290X.
Sapphire's triple fan cooler already made quite an impression on me when we tested a version of it on the R9 280X retail round up from October. It kept the GPU cool but it was also the loudest of the retail cards tested at the time. For the R9 290X model, Sapphire has made some tweaks to the fan speeds and the design of the cooler which makes it a better overall solution as you will soon see.
The key tenets for any AMD R9 290/290X custom cooled card is to beat AMD's reference cooler in performance, noise, and variable clock rates. Does Sapphire meet these goals?
The Sapphire R9 290X Tri-X 4GB
While the ASUS DirectCU II card was taller and more menacing than the reference design, the Sapphire Tri-X cooler is longer and appears to be more sleek than the competition thus far. The bright yellow and black color scheme is both attractive and unique though it does lack the LED light that the 280X showcased.
Sapphire has overclocked this model slightly, to 1040 MHz on the GPU clock, which puts it in good company.
|AMD Radeon R9 290X||ASUS R9 290X DirectCU II||Sapphire R9 290X Tri-X|
|Rated Clock||1000 MHz||1050 MHz||1040 MHz|
|Memory Clock||5000 MHz||5400 MHz||5200 MHz|
|TDP||~300 watts||~300 watts||~300 watts|
|Peak Compute||5.6 TFLOPS||5.6+ TFLOPS||5.6T TFLOPS|
There are three fans on the Tri-X design, as the name would imply, but each are the same size unlike the smaller central fan design of the R9 280X.

Tagged: amd, asus, ASUS ROG, MATRIX PLATINUM R9 280X
There is a lot to love about the ASUS ROG Matrix Platinum R9 280X, from its looks and faster and quieter performance when compared to the reference model. Still, [H]ard|OCP doesn't recommend running the fan at 100% except in brief moments when you need to dump heat quickly as it is quite loud but 50-60% will keep you below 90C and is not very noticeable. It overclocks very well, they hit 1270MHz core and 6.6GHz VRAM easily and noticed performance improvements when they did so, pushing past the GTX 770 occasionally. There is one major disappointment with this card, the price is currently over 50% higher than the base 280X MSRP so you might want to hold off for a while before thinking of purchasing this card.
"Today we take ASUS' elite R9 280X product, the ASUS ROG MATRIX PLATINUM R9 280X video card, and put its advanced power phasing and board components to the test as we harshly overclock it. We compare it to an ASUS GeForce GTX 770 DirectCU II. Then we will put it head to head against the overclocked SAPPHIRE TOXIC R9 280X."

Tagged: 2013, amd, nvidia, Intel, arm, qualcomm
2013 has been an incredible year and when looking at The Inquirer's look back on the releases of this year it is hard to believe that all of these releases took place in 12 short months. Haswell and Richland were the only two traditional CPU architecture updates for high powered desktop applications which stymied the enthusiasm of some gamers but the real star of 2013 was low powered silicon. ARM has always held strong in this market and celebrated several major releases such as 28nm dual core Cortex A15s and Qualcomm's raising of the bar on mobile graphics with the dual-core and quad-core Snapdragon 400 chips but they lost market share to three newcomers to the low powered market. NVIDIA's quad-core Tegra 4 SoC arrived with decent performance and graphics improvements compared to their previous generation and allowed the release of the Shield which has helped them become more than a GPU company that is also dipping its toes into the HPC market. AMD announced the G series of SoCs for industrial applications with a TDP in the neighbourhood of 6W as well as Temash which will power next generation tablets and hybrid mobile devices but it was really Intel that shone brightest at the low end. Bay Trail has completely reversed the perception of Atom from a product that is not really good at anything to an impressive low powered chip that provides impressive performance for small mobile devices and might find its self a role in the server room as well. That only scratches the top layer of silicon, click over for more of the year in review.
"While Intel and AMD battled out their ongoing war, Nvidia took the stage to announce its latest Tegra 4 system on a chip (SoC), a quad-core chip with a significant graphics boost. The firm did its best to play down the fact that its Tegra 4 has the same CPU core count as its previous-generation Tegra 3, and instead it focused on GPU performance, an area where the Tegra 3 was starting to look dated against newer chips from rivals such as Samsung."

Tagged: amd, Mantle, hawaii, BF4, battlefield 4
If you have been following the mess than has been Battlefield 4 since its release, what with the crashing on both PCs and consoles, you know that EA and DICE have decided that fixing the broken game is the number 1 priority. Gee, thanks.
While they work on that though, there is another casualty of development other than the pending DLC packs: AMD's Mantle version of the game. If you remember way back in September of 2013, along with the announcement of AMD's Hawaii GPUs, AMD and DICE promised a version of the BF4 game running on Mantle as a free update in December. If you are counting, that is just 1 more day away from being late.
Today we got this official statement from AMD:
After much consideration, the decision was made to delay the Mantle patch for Battlefield 4. AMD continues to support DICE on the public introduction of Mantle, and we are tremendously excited about the coming release for Battlefield 4! We are now targeting a January release and will have more information to share in the New Year.
Well, it's not a surprise but it sure is a bummer. One of the killer new features for AMD's GPUs was supposed to be the ability to use this new low-level API to enhance performance for PC games. As Josh stated in our initial article on the subject, "It bypasses DirectX (and possibly the hardware abstraction layer) and developers can program very close to the metal with very little overhead from software. This lowers memory and CPU usage, it decreases latency, and because there are fewer “moving parts” AMD claims that they can do 9x the draw calls with Mantle as compared to DirectX. This is a significant boost in overall efficiency."
It seems that buyers of the AMD R9 series of graphics need to wait at least another month to really see what the promise of Mantle is really all about. Will the wait be worth it?

Tagged: amd, firepro, SPECviewperf
SPECviewperf 12 is a benchmark for workstation components that attempts to measure performance expected for professional applications. It is basically synthetic but is designed to quantify how your system can handle Maya, for instance. AMD provided us with a press deck of some benchmarks they ran leading to many strong FirePro results in the entry to mid-range levels.
They did not include high-end results which they justify with the quote, "[The] Vast majority of CAD and CAE users purchase entry and mid-range Professional graphics boards". That slide, itself, was titled, "Focusing Where It Matters Most". I will accept that but I assume they did the benchmarks and wonder if it would have just been better to include them.
The cards AMD compared are:
- Quadro 410 ($105) vs FirePro V3900 ($105)
- Quadro K600 ($160) vs FirePro V4900 ($150)
- Quadro K2000 ($425) vs FirePro W5000 ($425)
- Quadro K4000 ($763) vs FirePro W7000 ($750)
In each of the pairings, about as equally-priced as possible, AMD held decent lead throughout eight tests included in SPECviewperf 12. You could see the performance gap leveling off as prices begun to rise, however.
Obviously a single benchmark suite should be just one data-point when comparing two products. Still, these are pretty healthy performance numbers.
The First Custom R9 290X
It has been a crazy launch for the AMD Radeon R9 series of graphics cards. When we first reviewed both the R9 290X and the R9 290, we came away very impressed with the GPU and the performance it provided. Our reviews of both products resulted in awards of the Gold class. The 290X was a new class of single GPU performance while the R9 290 nearly matched performance at a crazy $399 price tag.
But there were issues. Big, glaring issues. Clock speeds had a huge amount of variance depending on the game and we saw a GPU that was rated as "up to 1000 MHz" running at 899 MHz in Skyrim and 821 MHz in Bioshock Infinite. Those are not insignificant deltas in clock rate that nearly perfectly match deltas in performance. These speeds also changed based on the "hot" or "cold" status of the graphics card - had it warmed up and been active for 10 minutes prior to testing? If so, the performance was measurably lower than with a "cold" GPU that was just started.
That issue was not necessarily a deal killer; rather, it just made us rethink how we test GPUs. The fact that many people were seeing lower performance on retail purchased cards than with the reference cards sent to press for reviews was a much bigger deal. In our testing in November the retail card we purchased, that was using the exact same cooler as the reference model, was running 6.5% slower than we expected.
The obvious hope was the retail cards with custom PCBs and coolers would be released from AMD partners and somehow fix this whole dilemma. Today we see if that was correct.

Tagged: amd, 2014, beema, Kabini, FS1B
DigiTimes has put together an overview of AMD's plans to take back market share over the coming year, though of course AMD is not confirming or denying the accuracy of their report. First off will be the coming of the 28nm Kaveri family in January with availability planned to follow quickly. Beema, which will be based on the Puma+ architecture should arrive in the summer but there is also a Kabini-based series for the new socket, FS1B, which will get limited release in some areas. FS1B will be used for up coming Sempron and Athlon models designed for low power usage scenarios though don't expect to see AM3+ or FM2 disappear any time soon. You will have to wait for 2015 before Carrizo and Nolan make an appearance.
"AMD has been enhancing the marketing of its processors in DIY markets and aims to increase its global DIY market share from about 30% currently to 40%, and to reach a DIY market share above 45% in China in particular, at the end of 2014, according to Taiwan-based motherboard makers."
