Specifications of Athlon X4 "Trinity" CPUs confirmed
Presumably in October, AMD will introduce second generation desktop APUs with "Trinity" core. While one of the main features of this core is a greatly improved on-chip GPU, some "Trinity" processors will have the graphics unit disabled. These chips will be branded as Athlon II X4 or Athlon X4. Obviously, systems with these microprocessors will require discrete graphics cards to operate. In July, we posted some details on Athlon "Trinity" CPUs, and recently we were able to confirm our preliminary specs. Days ago, Gigabyte published specification of unreleased GA-F2A75M-D3H socket FM2 motherboard, that linked to a list of supported microprocessors. In addition to well known A4-, A6-, A8- and A10-Series APUs, the list contained details of Athlon X4 730, 740 and 750K. The motherboard page and the CPU support list were taken down since then, but the support information is still in Google cache.
The GA-F2A75M-D3H CPU support list shows exactly the same clock speeds, L2 cache and TDP for Athlon X4 processors as we published back in July. Also, the list confirms that the chips will not have integrated GPU. All Athlons come with 4 CPU cores and 4 MB L2 cache. The X4 730 and X4 740 SKUs are rated at 65 Watt TDP, and the 750K is a 100 Watt "Black Edition" part with unlocked multiplier. The 750K is also the fastest one: it runs at 3.4 GHz, whereas 730 and 740 models have slower 2.8 GHz and 3.2 GHz stock frequencies. At this time it's not clear whether the Athlon X4s will be introduced at the same time as A-Series APUs or not. Additionally, we couldn't locate Athlon X4 box part numbers, which likely indicates that they will be offered only as tray products.
