In terms of overall gaming performance, the Intel Xeon Processor X5355 is noticeably better than the AMD Athlon X2 7750 Black Edition 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.

The Athlon X2 7750 was released over a year more recently than the Xeon Processor X5355, and so the Athlon X2 7750 is likely to have better levels of support, and will be more optimized for running the latest games.

The Xeon Processor X5355 has 2 more cores than the Athlon X2 7750. With 4 cores, the Xeon Processor X5355 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Athlon X2 7750 and Xeon Processor X5355 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 Athlon X2 7750 has a 0.03 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 Xeon Processor X5355 has a 7072 KB bigger L2 cache than the Athlon X2 7750, and although the Xeon Processor X5355 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.

The Athlon X2 7750 has a 25 Watt lower Maximum TDP than the Xeon Processor X5355 (though they were created with the same size 65 nm manufacturing technology). What this means is the Athlon X2 7750 will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewAthlon X2 7750 Black Edition is a middle-class processor based on the 65nm, K10 architecture.

It offers 2 Physical Cores (2 Logical), clocked at 2.7GHz and 2MB of L3 Cache.
Among its many features, Virtualization is activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 95W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
Xeon X5355 is a Sever CPU released by Intel in 2006.
The performance is unimpressive considering the purposes it was built for but quite good for 2006.
Every game should run smoothly at high settings but Xeon X5355 wasn't built for gaming.
