This is mainly a result of the move to 28nm, and it should be balanced out by Kaveri's higher (on average) instructions per clock. Its clock speeds are also the highest of the bunch, but these are still less than the A10-6800K it replaces. The flagship chip, the A10-7850K, differs itself most obviously by its two extra compute units in the GPU, giving it a total of 512 stream processors compared to 384 in the parts below (although these aren't clocked any higher). It also has an unlocked multiplier, and you can see how we got on with that over the page. Performance margins between these will thus be small, especially in GPU-limited tasks, but the 95W TDP of the more expensive chip should allow it to boost more consistently. They share the same CPU and GPU hardware, and, with the A8-7600 in its 65W configuration, almost identical clock speeds, with the A10-7700K's 100MHz higher base clock being the only difference. Looking at the specifications, the A10-7700K emerges as quite an odd chip, in that it's barely different to the A8-7600.

As ever, programmers will need to write code in order to take advantage of this, but these features make Kaveri the world's first OpenCL 2.0 compatible chip, and AMD is keen to assert that the benefits will be widely felt in the future. One way this is achieved is through hUMA (heterogeneous Uniform Memory Access) whereby both elements have equal and shared access to the system memory, reducing the need to copy data in and out of two separate virtual buffers.ДЄnother way is hQ (heterogeneous Queueing), which means both the CPU and GPU can dispatch tasks to each other from within their own kernels, thus bypassing a number of overheads. The most significant architectural upgrade, however, is the use of HSA (heterogeneous system architecture), a hardware level solution that enables two or more processing elements (in this case the CPU and GPU) to communicate with a lot less overhead than traditional methods.

This brings with it support for Mantle (assuming it does actually arrive at some point), and AMD has also included its TrueAudio DSP for dedicated onboard sound processing. AMD is also utilising the latest revision of its GCN architecture for the GPU side, with up to eight compute units in a single chip. The main changes include a doubling up of the decode hardware at the front end and increases to the L1 instruction cache and branch target buffer. The Kaveri chip itself is 245mm 2 and comprises 2.41 billion transistors.Д¬lick to enlarge - The retail packaging for the new Kaveri APUsДЄMD has stuck with its x86 Bulldozer architecture but has made some optimisations for this third iteration, called Steamroller. These are backwards compatible with FM2 chips, but Kaveri APUs can only be used in FM2+ socket motherboards. Kaveri also brings with it the new FM2+ platform and accompanying A88X and A78 chipsets. Nevertheless, with Kaveri, AMD has moved its desktop APUs from a 32nm process to 28nm. Our A8-7600 review has tonnes of detail about Kaveri, so we're only glossing over the more relevant factors here. The -K suffix denotes that both chips have unlocked multipliers, so we'll be overclocking them as well (not forgetting that chips lacking this feature can still be overclocked via some BCLK tinkering). However, we've now got hold of both top end parts, the A10-7850K and the A10-7700K, so it's time to put them to the test. Our first exposure to AMD's new Kaveri APUs came, rather peculiarly, in the form of the as yet unreleased A8-7600, as the top of the range A10 samples were in short supply.

Thanks go out to Scan for supplying us with samples of both the A10-7850K and A10-7700K
