AMD has yet to move their CPUs to the 28 nm transistors, but the good old 32 nm is nothing to be sneezed at.
There are the A10-5800k, A10-5700, A8-5600k, A8-5500, A6-5400k, and A4-5300.
Apparently after Apple forgot to count with their iPad 3 and 4 — I meant: iPad and iPad with Retina Display, AMD decided that they would just completely skip a line or just remove the mobile processors and desktop processors from being in the same line.
Regardless of what they are numbered, the flagship (listed first), the APU is mostly impressive for the iGP that comes with it.
It sports 384 shaders at 800 Mhz. this with the 6570 (yay) with 480 shaders and 650 Mhz and it may at first seem a little lower, but when you remember that the 6570(40 nm) sells for anywhere between 50-80(with a cool cooler), the price tag that comes with the A10-5800k, a mere $130. The alternative for slightly better graphics and a normal CPU would force the CPU to be between $50 and $80. You’d have to go with a Sempron or Athlon, which are both outdated.
The Semprons mostly are single-cored, so those can’t really compete with the multithreading offered or higher clockspeed and higher IPC. The Athlons may at best be able to argue with the IPC, but the 4 core variant would be $75; 3 would be $70; the Athlon dual core @ 1.8 Ghz would fit the bill at $50(with discount).
So the A-series has some pretty good clockspeed, the lowest variant currently being 3.6 Ghz, which is still high; the highest base frequency is 3.8 with a turbo of 4.2 (and is overclockable).
Trinity has some IPC improvements over the Bulldozer, which was criticizing for not even getting the IPC that the older K10.5 (or was it K12) had(but with higher clockspeeds to make up).
All except the A4 support 1866 Mhz DDR3; the A4 supports up to 1600 Mhz DDR3.
The A10(k) outperforms the FX-4170 when it comes to gaming just by a little; it hits Intel home on integrated graphics tests.
Overall, the A-series looks pretty solid and affordable for the specs and performance.
