AMD FX-7600P Kaveri Review: FX Rides Again...In A Mobile APU?

Mobilizing Kaveri: The Product Stack

The first, most obvious change from AMD's mobile Richland design is DDR3-2133 support. That's technically not a new feature for Kaveri, which already accommodates fast data rates on the desktop. But it's certainly something we haven't seen before in the mobile space. Unfortunately, there's only one 35 W mobile APU with DDR3-2133 support; the rest cap out at 1866 MT/s. And the 17 to 19 W versions are validated for up to DDR3-1600.

Of course, the mobile version of Kaveri demonstrates different thermal behavior compared to the desktop implementation. AMD is actually leveraging the same kind of optimizations it exposed in the low-power Mullins and Beema APUs (Mullins And Beema APUs: AMD Gets Serious About Tablet SoCs). Many aspects of the SoC's utilization are monitored on a constant basis, and the goal is to provide quick, high boosts in frequency that dynamically respond to user input. Once a snappy response is achieved, the clocks quickly drop to lower levels, cutting power consumption and preserving thermal headroom.

AMD is trying to give the impression of fast, responsive performance, and our sample does seem to achieve that. Of course, this model falls apart when sustained, intense workloads are applied to the hardware. But all chip makers share the same challenge when it comes to high performance in small form factors.

New Brands: Mobile FX, and The AMD Pro Series APUs

Applying the FX brand to mobile APUs will no doubt raise eyebrows amongst enthusiasts. That moniker was already feeling watered-down after the Bulldozer generation let us down. In truth, this is simply a new top-tier sub-class for AMD's notebook-oriented hardware. Previously, A10 was used to suggest top-of-the-line. Now FX does that job, implying the highest available clock rates, functional units, and performance. Again, the FX-7600P distinguishes itself as the only APU with DDR3-2133 support, while the 19 W FX-7500 is limited to DDR3-1600.

In addition to the FX brand, AMD adds a new line of products to address the low-voltage commercial and business space. It dubs these the AMD Pro-series APUs, most of which appear to be re-badged versions of the ULV 19 W consumer models. The exception is the only dual-core Kaveri mobile model, the AMD A6 PRO-7050B. Of course, the Pro marketing message focuses on attributes that IT departments like to talk about: performance, longevity, and stability. It's a bummer that the Pro line-up doesn't include FirePro driver certifications, though AMD representatives concede this could become possible if the market (or certain customers) demand it. Why did AMD choose to bring a commercial version of its APU to market? AMD's Bernard Fernandes told us that it's a response to requests spurned by the increase in visually-oriented workloads. "We have made commitments to the image stability, product life cycle, and performance required in commercial environments with the AMD Pro A-Series APUs."

    20% IPC boost with Steamroller? (First page, second picture)

    That's enough for their 8-core chips to catch up or surpass current i5s, right?

    Awesome. If it was 5 years ago I would want a laptop and I would want this APU in it.

    Are we ever going to get some new CPUs for the AM3+ socket?

    I sure hope not. North Bridges and HT Link are so 5 years ago.

    Rather than posting what we already know will be crappy framerates of recent games I wish that when outlets reviewed iGPUs they used some old games to see how those would run. Nobody buys a mobile APU expecting to use it for Battlefield 4. But people do like running older games on their APUs because those will most likely run decently. It would be nice to see how something like Final Fantasy XI or Knights of the Old Republic would run on this. Final Fantasy XI even has a benchmarking tool called Vana'diel Bench 3.

    45w tdp on notebook. i think will we see some 17" + notebooks. don't put on your legs or you fry it!

    I agree, though it still makes sense to keep one demanding game in the test suite to give perspective on where this hardware stands compared to dedicated graphics cards and high-end CPUs.

    Thanks for including Dota2 Benchmarks. I had experienced FPS drop on my current Laptop(almost dead with i5-450M and HD5470, 1366*768, 4GB RAM) due to overheating, I tried to reduce resolution and tried many configs, but the problem was there.I have let Raptor(AMD 's app) to adjust the profile for Dota2, after that I didn't face the problem.

    So the performance can be equal to i5 M processor.

    I miss 720p testings that is the resolution a clever player would use with this GPUs
    1080p and demanding games are not good benchmarks for this GPUs you must use less demanding games or test lower resolutions It is not the same benchmarking F1s than Nascars or electric cars

    if you are looking for a budget gaming laptop no doubt the 7600p is a good choice all the way around.

    That's why we used Dota2, Grid2, and WoW... they have low system requirements, and ran fine. ;)

    So... how about that desktop A8-7600...

    Over at Anand they said the GPU drivers were slightly older, Mantle isn't enabled properly in them. Could be why the numbers between DirectX and Mantle are pretty much the same

    Mantle only shows an advantage in Battlefield 4 in rare cases, regardless of the driver. The game also requires a ton of VRAM for Mantle to show a gain instead of a loss. I have an in-depth analysis coming soon.

    Having said that, Thief shows impressive gains across the board in Mantle.

    We *did* use 720p where the graphics processor couldn't handle it... in Battlefield 4

    The FX-7600P worked fine at 1080p with Dota2, Grid2, and WoW, so why would we lower the resolution?

    I take great pride in testing at real-world settings, and I often lower to 720p when 1080p is too demanding.

    The only thing missing from this that I would find is the real deal breaker: what is the power consumption?

    “AMD is trying to give the impression of fast, responsive performance, and our sample does seem to achieve that.”

    “That top-of-the-line FX-7600P is a completely functional Kaveri APU, with both of its Steamroller modules (four integer cores) and all 512 of its shaders enabled.”

    “While AMD appears confident in the ULV Kaveri's ability to compete against Core i7-4500U, the higher TDP meant we needed to find an Intel-based platform with a comparable thermal ceiling. I tapped the 37 W Core i7-4702MQ within Acer's Aspire V3.”

    37 W Core i7-4702MQ this a 380$ dollar part……….. way more than Kaveri

    No Firestrike score.

    I would prefer different benchmarks.

    Hi h2323, great to see you again. I took the liberty of erasing your unproductive rhetoric to address your actual concerns:

    1. You've listed the top three quotes with no comments beside them. Not sure what kind of point you're trying to make, there. Does that mean you like them?

    2. AMD didn't provide pricing, so we compared a mobile Core i7 part with similar wattage AS PER AMD's DIRECTION. If you disagree with their decision, I encourage you to contact their PR team.

    3. I can only assume you have no idea what Firestrike is for. As per Futuremark:

    "Fire Strike is a showcase DirectX 11 benchmark designed for today's high-performance gaming PCs. It is our most ambitious and technical benchmark ever, featuring real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks and games today."

    Mobile integrated GPUs are not "high performance gaming PCs". Would you find it valuable to see benchmark results of a slideshow? We wouldn't.

    4. You indicated that you would prefer different benchmarks, but didn't mention which ones, or why?

    Have a great day! :)

    Disregard for AMD strengths and Firestrike was not included because the Intel chip was likely unable to run it.

    Granted most of the tests in that review focus on gaming but AMD's not half bad in everyday tasks. Considering the price of i7-4702MQ, I feel its too expensive to be compared.
