[TPU] AMD Trinity (Piledriver) Integer/FP Performance Higher Than Bulldozer, Clock-for-Clock

AMD's upcoming "Trinity" family of desktop and mobile accelerated processing units (APUs) will use up to four x86-64 cores based on the company's newest CPU architecture, codenamed "Piledriver". AMD conservatively estimated performance/clock improvements over current-generation "Bulldozer" architecture, with Piledriver. Citavia put next-generation A10-5800K, and A8-4500M "Trinity" desktop and notebook APUs, and pitted them against several currently-launched processors, from both AMD and Intel.

Unfortunately, a 10% improvement will not save the Bulldozer arch...

I was expecting a lot more from Piledriver but yeah... whatever AMD.

Let's hope the actual Piledriver CPUs will be better.

OK so it's back on par with Phenom II?

Yeah... more or less. Unlike Nvidia's Fermi which was not that great at first and eventually became fantastic, AMDs Bulldozer seems to mature quite badly.

Sadly the guy from the original source has his calculated % in a strange way (not one of correct right ways, or maybe those numbers are for something else?)

Integer It is actually clock for clock 17% better than bulldozer (5800K vs 8150), and that is without L3 cache.


FP is 13% better.


Worked out by (numbers for 8150 vs 5800K, clock for clock):

INT: 1978.6/100 = 19.786
2327.4/19.786 = 117.6
117.6 - 100 = 17.6%

FP: 619.5/100 = 6.195
701.2/6.19 = 113.18
113.2 - 100 = 13.2 %

Which is actually really impressive, wow, if this performance comes true ill probably be looking to upgrade.

Eh? The GTX 580 was only like a 15% improvement over the 480. This is a lot more than 15%... it's moving up ~10% in IPC and in moving up in clock speed as well. It's practically a guarantee that Vishera will clock higher than BD.

Makes me sad to see little improvement for Piledriver, but this isn't officially the main CPU line, so tihere is still hope.

Edit: seeing as Trinity will be for lower-tiered builds and laptops, this is actually very good performance. It looks good for laptop gamers.

Nice the A10 is more powerful than the 2920xm.
Is the A10 a mobile chip?
Either way i cant wait, AMD is more powerful with math based calcs.

I'm curious why you wouldn't go for the better CPUs in that test, like the 2500k, which seems be leaps and bounds ahead in most categories, especially clock-for-clock.
