AMD and Intel, in the last few years, have taken different approaches to how many CPUs enter the mainstream line of the market. Intel has historically had a large product stack, with processors at almost every frequency varying by 100 MHz and slowly rising in core count as well as cache and integrated graphics. AMD’s approach on the other hand is to release a handful of new models every quarter, initially covering the bases on day one and slowing updating the mid points (as well as new high end models) as a lithography node improves in yield and performance and the design matures. We recently took a look at the last launch, the AMD A10-7870K, as well as one at the beginning of the year in the shape of the A8-7650K. The A10-7870K was the first in a line known as the Kaveri Refresh models, or as per AMD’s internal codename ‘Godavari’. The A8-7670K is the second iteration of this line.

The Kaveri Refresh line, or so we are told, is a result of an improved production methodology for better frequency/voltage characteristics and better binning. In the case of the A10-7870K, we were told that the CPU has a minor +0.05 volt increase in the average stock voltage to account for the extra frequency, but due to the improvements the TDP remained the same (95W). In this circumstance, AMD improves on the A8-7650K with an extra 300 MHz to the base frequency (usually the main TDP killer) and an extra 100 MHz on the turbo. This is combined with a 37 MHz increase in the graphics side of the equation, again within the same TDP.

We covered a lot in the A10-7870K review which also applies here to the A8-7670K, although the A8 follows the other A8 APUs by having six compute units for the graphics, or 384 SPs. As AMD does not have a new mainstream desktop APU launch for Windows 10, the current stack of Kaveri and Kaveri Refresh APUs are going to be the focus for AMD, especially with back-to-school sales late in the summer. As a result, a good portion of the press release for the A8-7670K revolves around the use of AMD’s GCN architecture and its alignment to AMD’s mainstream graphics cards, allowing any software that is accelerated by one to be accelerated by the other. As shown above, this includes video playback, DirectX 12, accelerated video encoding and streaming as well.

AMD’s marketing slides position the A8-7670K at $118 MSRP against the i3-4160 at $120 – and as a result we see benchmarks that require four full INT cores (7-zip), or those that rely on the GPU for part of their compute (PCMark 8), coming ahead. When compared to a discrete GPU solution, AMD suggests that an equivalent cost to the A8 is an Intel Pentium G3258 with a GT 730 discrete card, where the discrete card loses in popular eSports gaming titles. As has been the case for AMD, they play to the strengths of their product, and these lie in that sub-$700 gaming PC (based on the A68H platform) built for eSports that should also help with future DirectX 12 multi-GPU rendered titles.

The AMD A8-7670K is officially launched today and currently retails at $110 on Newegg, making it cheaper than the official MSRP. If we get a sample in, we’ll write a review and add the data to our processor comparison database Bench.

    Umm does amd have cpu with ddr 4 on die for the gpu. I don't think a small frequencies change will really help much. Reply

    I love how the A8-7670K is faster and better than the A10-7700K in every regard. They really screwed up the naming consistency with that SKU. The A level should always be used to differentiate the number of funtional units like when the APUs were first launched. Reply

    SO DAMN WEAK!!! AMD IS CRAP SO SLOW COMPARED TO INTEL Reply
