With little fanfare, AMD has released some details on its first desktop-bound Trinity APUs. These chips will be based on the same quad-core design as AMD's mobile Trinity APUs, complete with Piledriver CPU cores and updated Radeon graphics. The desktop parts will run at higher speeds, though. Here are the specifics on the incoming models:
|Model||Base clock||Boost clock||IGP||ALUs||GPU clock||TDP|
|A10-5800K||3.8GHz||4.2GHz||Radeon HD 7660D||384||800MHz||100W|
|A10-5700||3.4GHz||4.0GHz||Radeon HD 7660D||384||760MHz||65W|
|A8-5600K||3.6GHz||3.9GHz||Radeon HD 7560D||256||760MHz||100W|
|A8-5500||3.2GHz||3.7GHz||Radeon HD 7560D||256||760MHz||65W|
All the CPUs feature quad cores (two modules), 4MB of L2 cache, and support for DDR3 memory speeds up to 1866MHz. The chips slip into AMD's FM2 socket, which means new motherboards will be required. Overclockers will want to pay attention to the K-series models, which feature unlocked multipliers.
While the A10-5800K's 4.2GHz Boost clock is impressive, that probably won't be enough to match the CPU performance of Intel's dual-core Ivy Bridge processors. We've already seen the Core i7-3770K dominate the FX-8150, an eight-core Bulldozer part that also peaks at 4.2GHz. It seems unlikely Trinity's per-clock performance improvements will be substantial enough to close the gap.
These first desktop Trinity models will appear in all-in-one PCs starting this month, according to AMD.
That's interesting, because at Computex last week, numerous motherboard makers told us the desktop Trinity parts were delayed. Looks like big-name PC makers have first dibs on Trinity chips, although this silicon might not be the same as the chips destined for retail-boxed APUs, which are purportedly due this fall. We're told by a trusted source that AMD is respinning the silicon for a collection of desktop Trinity parts to be released in October.
