This week, the company introduced three variations of the A-series "accelerated processing units" (APUs). The A4 has two of AMD's "Stars" CPU cores (the same core used in the existing Athlon, Phenom, and Turion chips) running at 1.9 GHz, with the ability to reach a "boost" speed of 2.5 GHz and with 2MB of level 2 cache and 260 Radeon graphics cores. The A6 is a quad-core version running at 1.4 GHz, with a boost speed of 2.3 GHz with 4MB of level 2 cache and 320 graphics cores. The A8 takes the quad core to a 1.5 GHz base frequency and a boost speed of 2.4GHz and has 400 graphics cores. All are designed to be 35 watt chips.


Note that you can't use "graphics cores" as a comparison among the different vendors, since they count them differently, but within the vendor, the number is a very good indication of top graphics performance.

As I mentioned Tuesday, AMD is positioning these chips as having better graphics performance--including Direct X 11 support--than the Intel "Sandy Bridge" Core chips and better battery life than AMD's previous generation of chips. On the other hand, the Sandy Bridge chips tend to do better on CPU benchmarks, so your overall performance is likely to vary depending on application.

I find it kind of interesting that they're dropping the Bobcat cores down to 28nm before the Bulldozer cores.

theres probably a test run bobcat is a derivitive of stars if i remember correctly so since there a less complex design means less likely for something to go wrong on 28nm cpu so im guessing its much like the 4770 was for AMD gpus side of things when 40nm hit.

That makes sense.

28nm is the half-node of 32nm and AMD have stated that they will not make their high-end cpu's on half nodes only gpu's and low-power cpu's.

wasn't bocbcat supposed to be a derviative of bulldozer?

According to this,

Bobcat is it's own architecture meant for very low level devices.

bobcat is a stripped down k10.5, likely has more in commons with the old k8's with the improvements in k10 series cpus. JfAMD covered this on anandtech.com a while ago.

Link please? I would love to read it.

I dunno, I don't go over there much but its in the cpu/overclocking subforum. Just search for jfamd posts on bobcat. Shouldn't be many of them.
