FX-8350 Tuning With AMD's Open64 Compiler

Phoronix takes a look at tuning with the FX-8350 and AMD's Ope64 compiler.  

In the GCC Piledriver tuning tests from last week with GCC 4.7.2 I went over what the bdver2 target adds: BMI, TBM, F16C, and FMA3. FMA3 is a three operand variant (that's being pushed by Intel with Haswell) of Fused Multiply-Add rather than the four operand version, F16C allows for converting and storing 32-bit floating point values using 16-bits, TBM is Trailing Bit Manipulation, and BMI is Bit Manipulation Instructions.

CPU Price War Coming

Over at Fudzilla they expect a CPU price war is coming soon.  With Trinity out and CPU sales dormant that is the only way to move kit.

AMD has priced the Trinity chips starting at $53 in quantities of 1,000. Its new new dual-core A4-5300 desktop processors are priced at $53, which is the lowest of all Trinity desktop chips. It is much lower than the Intel Core i3 processors, which are based on the Ivy Bridge microarchitecture and start at $117.

CPU Price Stagnation Explored

Tech Report looks at CPU price stagnation.  Intel prices don't budge since AMD has been unable to mount effective competitors in the mid and high range.  You of course do not see this in GPUs.

Going as far back as 2009, it's clear AMD's mid-range processors have consistently followed a downward pricing slope. Their plots make me think of rainwater trickling down a mossy bluff. That bluff has only been getting steeper since the debut of Intel's Sandy Bridge processors in early 2011. For the most part, Sandy Bridge's arrival forced AMD to compete on price rather than performance in this segment. Ivy Bridge only made matters worse. The deep cuts to the FX series after the Ivy Bridge debut earlier this year are clear evidence of that.

AMD Trinity Update

 

AMD just set out the following about the upcoming Trinity desktop launch.

October 2nd marks an exciting new chapter in modern processing history!

The next generation AMD A-Series Accelerated Processing Units, codenamed Trinity, will soon be available for the first time in the channel. Be the first to order on October 2nd.

With more cores, more speed, more graphics and more upgradability, everything that was already so innovative (APU = CPU + GPU) about the first generation A-Series APUs is now that much more entertaining.

More Cores and Speed
Up to 10 cores (4 CPU + 6 GPU)
Up to 900MHz more per part than the competition (AMD A10-5800K APU vs. Intel Core i3 3220 Processor)
Overclock for Even Higher Frequencies...Break the 1GHz barrier on the GPU!1
Best Entertainment

3X the compute of a traditional CPU2
More FPS and 1080p gaming
Better Looking HD Videos
Easy Upgrade Path

Enhanced performance capabilities and platform longevity with FM2 motherboards for future upgrades
Up to 75% boost on select graphics cards with AMD Radeon™ Dual Graphics3
AMD Memory Profile Support for automatic performance
Why Sell Trinity APUs?
What the Experts are Saying about Trinity4

“Granted the 29 percent CPU performance boost is pretty impressive, but it's that 56 percent increase in the GPU that will be of most interest to gamers. Whether you're a casual gamer who likes playing web-based games or a hardcore gamer who stands in line for every new release in the Call of Duty series, the GPU inside the new A-series APU genuinely lives up to AMD's label of ‘discrete-class graphics.’”
– Jerry Jackson, Notebook Review

“AMD has a very credible chip on their hands with Trinity, and Intel should be very worried.”
– Charlie Demerjian, SemiAccurate

“The final factor for AMD’s Trinity processor is price, which is where the chip shines brightest.”
– Scott Nichols, TechRadar

The Bottom Line

The next generation “Trinity” A-Series APUs provide even more features for the dollars (cores, frequency, upgradeability)...even more opportunity for tweaking and overclocking...and are better than ever at performing the compute-demanding activities (entertainment, gaming) today’s customers care most about.1

1. AMD's product warranty does not cover damages caused by overclocking, even when overclocking is enabled with AMD hardware or software
2. GFLOPs calculations developed by AMD performance labs measuring compute capacity for the AMD A10-5800K APU with AMD Radeon™ HD 7650D Graphics which is 736 GFLOPS. GFLOPs calculated using GFLOPs = CPU GFLOPs + GPU GFLOPs = CPU Core Freq. (3.8GHz) X Core Count (4) X 8 FLOPS + GPU Core Freq.(800MHz) X DirectX® 11 capable Shader Count (384) X 2 FLOPS.
3. Testing conducted by AMD performance labs using Diablo III @ 1920x1080, Maximum settings, shadows medium. Test configurations: AMD A10-5800K APU with AMD Radeon™ HD 6570 Graphics using 2x4GB DDR3-1866 with Windows® 7 64 bit scored 34 fps, while the same system with AMD Dual Graphics Mode enabled scored 60 fps.

AMD Demos FX-8350, A10-5800K Near IDF

Techpowerup has details about AMD's demo of the upcoming FX-8350 and A10-5800K near IDF yesterday.  Have we ever seen any of these CPUs?  Maybe, but not at IDF.  Game Republik is taking up too much of my time as well as are my daughters to make it out this year.  Maybe CES.  Maybe.  

The FX-8350 was shown installed on a machine with ASUS Crosshair V Formula (-Z?) motherboard, liquid cooling, and Radeon HD 7970 graphics card. The chip was clocked at 5.00 GHz (4.80 GHz when the picture was taken), and running popular CPU-intensive benchmarks such as WPrime and Cinebench. The A10-5800K was shown running application demos, including a widget that displays real-time boost states of the processor and GPU cores.
