AMD leaks mobile Kaveri line-up

Written by Peter Scott



Lots of quads, ULV parts

Earlier this week Computerbase.de came across the first mobile Kaveri, specced in an HP laptop service guide.

The A10-7300 is just the first in a line of mobile Kaveri parts. It’s a 19W quad-core clocked at 2GHz, or 3.2GHz on Turbo. The spec points to a significant clock bump, made possible by the tweaked design and the transition to the 28nm process.

The A10-7300 is not alone and now we know that it’s in good company.

Seven mobile Kaveri APUs are coming


The first batch of mobile Kaveri APUs consists of seven parts, six quad cores, one dual core, including four ULV parts and three 35W parts. The leak comes from a familiar source, Computerbase.de

In the ULV segment the A10-7300 is joined by three new parts. The FX-7500 is a 19W quad-core clocked at 2.1/3.3GHz. Like the A10-7300 it packs 384 Radeon cores. The R7 GPU is clocked at 496/553MHz and the APU supports DDR3 1600 memory. 

The A8-7100 is another 19W part. It’s a quad-core clocked at 1.8GHz, up to 3.0GHz on Turbo. It has R5 graphics with 256 cores clocked at 450MHz/514MHz. The A6-7000 is the only dual-core in the mix. It runs at 2.2GHz base and 3.0GHz Turbo. It’s a 17W part with the weakest GPU of the lot, an R4 with 192 cores clocked at 494/533MHz.

All ULV Kaveris support DDR3 1600 memory. All quad cores feature 4MB of L2 cache, while the A6-7000 comes with just 1MB.

35W parts with up to 512 GCN cores


In addition to the 17W/19W parts, AMD has also cooked up three mainstream 35W APUs.

The A8-7200P is clocked at 2.4/3.4GHz. It has R5 graphics with 256 shaders clocked at 553/626MHz. It supports DDR3 1866. The 10-7400P is marginally faster at 2.5/3.4GHz, but it packs R6 graphics with 384 shaders clocked at 576/654MHz. Like its sibling it supports DDR 1866 memory.

The leader of the pack is the FX-7600P. It runs at 2.7GHz base and 3.6GHz turbo. It is the only mobile Kaveri to feature R7 graphics with 512 shaders. The GPU runs at 600/686MHz. Although the GPU clocks are somewhat lower than on desktop Kaveri APUs with all 512 shaders, the new FX appears to have the most powerful integrated GPU of any mobile part to date. It is also the only mobile Kaveri to support DDR3 2133 memory. Keep in mind fast memory tends to have a good effect on APU GPU performance.

The line-up looks good, with the biggest gains coming in 19W and 17W parts. Due to Intel’s process lead, ULV performance was always AMD’s Achilles heel. While Kaveri won’t match Haswell parts in the CPU department, the clocks are quite a bit higher than on comparable Richland parts and we should see some nice performance gains.

We also like AMD’s decision to introduce FX branding for select mobile APUs. AMD fans know what FX is supposed to stand for and while some puritans could argue the brand should only be used on high-performance desktop parts, we don’t mind seeing it on mobile chips. A simple two letter prefix now denotes the fastest parts in both thermal envelopes, one notch above the A10 series.
