Conclusion: Now that we have had a closer look and ran some benchmarks; are these APUs a worthy purchase? Do the specifications on paper live up to worthy real world standards? There is only one way to find out but first, let’s take a look at the difference between the AMD A10-7850K and A10-7700K APUs.
AMD A10-7850K (Kaveri) Review: One Step Forward, Two Steps Back
13 May 2014
Summary: AMD Kaveri has united four x86 Steamroller cores and GCN-based Radeon R7 graphics core. It has manufactured by 28-nm process technology and supports HSA specification. AMD believes that due to this cocktail it has an outstanding product, able to compete with Core i5. But according to the results of the tests we have a different opinion.
Conclusion: AMD’s Kaveri A10-7850K is a solid overclocker. While we settled at 1028MHz on the GPU we were able to go another divider higher with slight bumps in voltage and the enthusiastic overclocker might even be able to go a couple more dividers up into the 1100-1200MHz region. What a difference the 308 MHz extra made. Pairing up our overclock with fast RAM saw us making large gains in most GPU-centric applications.
Summary: System Benchmarks -
The A10-7850K, through the use of compute cores and HSA computing, showed considerable improvement in most tasks. The only place where it would be considered stagnant is with pure x86 processes, where it is still on par with the previous “Richland” processors. With “Kaveri”, the Radeon R7 GPU cores are based on the Hawaii GPU.
Cons: Low Priced, HSA Computing Looks Promising, Overall Improved Performance, 4.5GHz Overclock, Good Temperatures, Improved Video Performance, Unlocked, Low Power Consumption, 1080p Gaming On Low settings With No Discrete GPU, Up to Date Dual-Graphics Configuration, GPU Supports Mantle API
Conclusion: So while Kaveri holds some promise for AMD, its top-end chip occupies a precarious spot in the current field of desktop CPUs. It makes sense in a few niche situations, but it lacks broader appeal due to its price, high power consumption, and features that are probably too far ahead of their time for a chip that feels dated in areas like power efficiency and CPU performance.
Pros: Integrated graphics can handle most games at 1080p and medium settings, Unlocked for overclocking
Cons: Much higher TDP than comparable Intel CPUs, Fastest possible RAM required for best gaming performance, CPU performance still lags behind the competition, HSA support currently limited
Summary: Kaveri APus have a lot in store, and get a lot to say about. I've been working with this A10-7850K APU for a few days now and its an excellent APU for generic desktop PC usage. Combine your setup with a nice SSD and the OS feels incredible snazzy and fast. Next to that , I was just trying out Battlefield 4 playing on the integrated GPU. Though the results are not injected into our test suite, on average at 1080P I got 25 to 30 FPS at medium quality settings.
Conclusion: Although the A10-7850K's CPU was only around 5% faster than the A8-7600 and typically slower than the A10-6800K , the A10-7850K's gaming performance was superior in each of the six titles tested. There's no denying that the A10-7850K has the most powerful integrated graphics available, yet it's never going to be the average gamer's first or even fifth choice with cards like the $150 Radeon R7 260X around.
Conclusion: AMD's A10-7850K represents the very best APU of this generation. Design decisions taken years ago mean that while the architecture of the CPU and GPU components is arguably better than last-generation Richland (A10-6800K), this new Kaveri APU is not clocked in as high on either front. Folks who need excellent CPU performance need to look at Intel's price-comparable offerings... spend a little more and there's very little doubt that the Core i5-4670(K) is a better bet.
