AMD Kaveri Mobile APU, FX-7600P Preview

Article Index:   
A full complement of Kaveri mobile cores is 12 total--four CPU cores and 8 GPU cores.  AMD refers to all cores as "Compute Cores" and specifically, on the highest-end variant of Kaveri for notebooks, there are 4 Steamroller CPU cores and 8 AMD GCN-based graphics cores.  These GPU cores are also based on AMD's latest architecture found in their Hawaii GPUs, which includes AMD's TrueAudio technology for multi-directional output, signal enhancement and noise removal.

With Kaveri, AMD is claiming a significant performance uplift in both CPU and GPU performance.  Obviously, GPU performance comes courtesy of the aforementioned GCN GPU technologies, but Kaveri's Steamroller CPU core architecture brings beefed-up resources in a number of areas as well. According to AMD, with Steamroller, mispredicted branches have been improved by about 20%, scheduling efficiency by 5-10%, and i-Cache misses by up to 30%.  Combined, Kaveri's fetch, scheduler and cache enhancements can offer up to a 20% IPC (Instructions Per Cycle) uplift over the previous generation of AMD's Richland architecture.

Here we see AMD's positioning of their Kaveri mobile line-up versus chief rival Intel.  At the top of the stack is the AMD FX mobile series; we actually tested an AMD FX-7600P, which is a 35 Watt variant, the fastest Kaveri mobile chip there is currently. The FX-7600 has 8 GCN GPU cores.  However, looking at the product map here, AMD is positioning a 19 Watt variant of Kaveri, the FX-7500, versus Intel's 15 Watt Core i7-4500U.  While unfortunately we don't have this match-up to show you on the following pages, from a CPU clock speed and GPU core count perspective, we should be able to extrapolate approximate performance expectations.

Probably the most mainstream Intel SKU we've seen in the wild for ultrabooks as of late, has been the Core i5-4200U.  Here AMD is matching up their 19 Watt TDP A10-7300 which has 6 GCN cores and a four CPU cores clocked at 1.9GHz with a 3.2GHz max. turbo speed.  Again, Intel's Core i5-4200U does technically drop in at a lower 15 Watt TDP, however, so it will be interesting to see how battery life shapes up once we get some hands-on time with retail-ready notebooks based on AMD's new Kaveri mobile silicon.

For now, let's look at our test vehicle for this preview, some quick APU vital signs and top-end performance with AMD's FX-7600P Kaveri mobile APU.

My moneys is still on the Tegra. Intel & AMD are too busy fighting to notice that nVidia is making their move to dethrone them!

Do you think you'll see Tegra-based notebooks any time soon?

Let me know when Tegra based laptop can play a real PC game and has a real JVM for me to code with.

It's only 2.7/3.6GHZ quad core with less work done per clock cycle than Sandy Bridge+, and 35W TDP. AMD needs to grow a pair and release some 47W and 57W APUs like Intel has done so it can have more room for performance with laptops.

That too funny. Most of the time the call is for AMD to reduce TDP and thermals, not raise them.

Sure looks like AMD Red Team is delivering the multimedia performance and gaming goods in the laptop arena. Considering a price to performance ratio, the mobile "Kaveri's" look like a "Smackdown" with plenty of game at this time.

How about comparing apples to apples rather than apples to grapes?

Put some data up for the i7 47W chips (which usually take as much power as the AMD 35W ones), like the Iris Pro ones (i7 4950HQ)? Or at least the i7 4650U with GT3 and 3GHz turbo, that should have a 50% advantage over the i7 4500U minimum (and possibly double, though doubtful without increasing TDP tolerance)

Along with a commensurate 50%+ increase in price LOL.

"Along with a commensurate 50%+ increase in price"

You would be surprised, even if the chip itself costs 100% more the total price won't increase nearly as much (usually other parts are also improved). Not to mention that simply having a 15W i5 with discrete card will out perform anything else while still drawing less power at idle.

I just bought an AMD A10 based toshiba notebook and I'm quite amazed at the performance I got for the price.

Amazed in a good way. takes a whole 4 seconds to boot and plays most games very well, especially considering it had only the integrated GPU, but I can run most new games ESO, the new Wolfenstein etc with most settings up high. Have to play with the OverDrive software and see what headroom there is for overclocking (probably not much).

"It all comes down to final price points and real-world system performance."

That is the point. Sell to more people who need something new that works well and can't afford the best. (or don't need the best)

AMD is crazy like the Fox.

still think apu processors are the way to go for budgets

This laptop is great for regular gamers and pc users who dont need ultra graphics the only thing im concerned about is price
