CPU Mini Review

Mini Review AMD A10-5757M is a mobile Quad Core processor, part of AMD's APU processors based on Richland, and thus fabricated using a 32nm technology. It sports four cores, clocked at 2.5GHz, and reaching 3.5GHz in Turbo Mode. This APU features the Radeon HD 8650G, clocked at 600MHz, which goes up to 720Mhz when Turbo is enabled. It supports DDR3-1600MHz RAM, and its thermal design power is only 35 watts. Compared to A10-5750M, this processor's onboard GPU is clocked at a higher base frequency, however the maximum memmory supported drops from 1866Mhz to 1600MHz. Core i7-2670QM 4-Core 2.2GHz is a high-end mobile CPU based on the 32nm, Sandy Bridge architecture. It offers 4 Physical Cores (8 Logical), initially clocked at 2.2GHz, which may go up to 3.1GHz and 6MB of L3 Cache. Among its many features, HyperThreading, Turbo Boost and Virtualization are activated. The processor integrates relatively weak Graphics called Intel HD i7 2670QM, with 12 Execution Units, initially clocked at 650MHz and that go up to 1100MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor. Both the processor and integrated graphics have a rated board TDP of 45W. Its performance is very good and sufficient for any of today's games.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i7-2670QM 4-Core 2.2GHz is massively better than the AMD APU A10-5757M Quad-Core when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the APU A10-5757M Quad-Core and the Core i7-2670QM 4-Core 2.2GHz were released at the same time, so are likely to be quite similar.

{ The APU A10-5757M Quad-Core and the Core i7-2670QM 4-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

The Core i7-2670QM 4-Core has 4 more threads than the APU A10-5757M Quad-Core. The APU A10-5757M Quad-Core has one thread per physical core, whereas the Core i7-2670QM 4-Core uses hyperthreading and has 2 logical threads per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The APU A10-5757M Quad-Core and Core i7-2670QM 4-Core are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the APU A10-5757M Quad-Core has a 0.3 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. As such, we need to look elsewhere for more reliable comparisons.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The <span class='gpu1Mention'>APU A10-5757M Quad-Core</span> has a 3072 KB bigger L2 cache than the <span class='gpu2Mention'>Core i7-2670QM 4-Core</span>, and although the APU A10-5757M Quad-Core does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.
