[HH] AMD Fusion APU and Graphics Update: Trinity - Page 3

post #21 of 75
me want
post #22 of 75

Quoted from this article posted earlier:

Update:  AMD has stated Trinity will deliver a 25% increase in CPU performance and a 50% increase in GPU performance.  Stay tuned to PC Perspective for more Trinity info as it develops.

 

A 25% increase in CPU performance, considering this is compared to the previous Llano APU which uses Phenom II cores (which do have higher IPC than AMD FX cores and equivalent instructions-per-second when both are overclocked), that actually sounds very, very good to me.  GPU performance increase sounds exciting too!  I worry however that both these improvements will not be seen to their full extent as more RAM bandwidth will be needed!  The Trinity APU will force RAM to move forward from DDR3-1066/1333.  With DDR3-1600 starting to become common in laptops however things might change.

 

I think I will be choosing a Trinity APU laptop this summer when I get one thumb.gif

AMD's current 17W APU's are the E-300, E-350, and E-450. All of those have 80 SP's on die. 50% gain over that is not too much. 25% gain over E-450 is still slower than Core 2. On the other hand, Ivy Bridge ULV lineup has been released, the i5's will have a dual-core turbo around 2.5ghz.. with ~5% IPC gain over SB. HD 4000 is about 50% faster than HD 3000, which is much faster than E-350's 6310. Am I missing something or is Trinity the catch-all for AMD's mobile APUs, instead of seperating it with 2 different lines (like currently, 35-45W Llano and 17W Brazos).

If they are comparing to a dual-core A4, then it's not impressive. If they are comparing to a quad-core PhII, then a 25% increase in CPU performance on the same fab with fewer "real" cores is a bit more impressive depending on clockspeed.

It's nice to see AMD pushing those RAM speeds. Bumping RAM speeds will net significant performance improvements with current APU. I guess the extra speed was needed to help with the 50% extra GPU power.

I'm taking the wait-and-see approach.

IIRC, AMD killed it's 28nm E-series linup (GF couldn't make the chips to spec and a complete redesign would be needed to switch to TSMC due to differing manufacturing methods (but time to market would be too long))

Just like Intel, AMD has been working on dropping the power consumption of processors (esp. by dropping clockspeed).

Side note: Zacate is made on a bulk 40nm process. Using a more refined process like the one used for Llanos/Trinity would give much better performance while using less power, but the cost would be driven up (probably from $8 to $40) by switching (not including the redesign time and costs). Switching to a LP 28nm would hurt performance too much, so that's not an option either.

this is great, now i'll be able to continue my pattern with buying products.

intel = high end desktop
amd = high end laptop


this is great stuff man, so proud of the underdog here

So less GPGPU potential but still good graphics potential? I was hoping for Trinity to really push the APU idea and not just be an integrated GPU frown.gif

trinity, at least in desktops(afaik) will support up to ddr3-2133.
llano on desktop supports up to ddr3-1866, but only up to ddr3-1600 on llaptops. biggrin.gif
