In terms of overall gaming performance, the Intel Core i7-860S Quad 2.53GHz is noticeably better than the AMD Phenom II X4 B65 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 Phenom II X4 was released less than a year after the Core i7-860S Quad, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Phenom II X4 and the Core i7-860S Quad both have 4 cores, which is not likely to be a limiting factor for gaming.

The Core i7-860S Quad has 4 more threads than the Phenom II X4. The Phenom II X4 has one thread per physical core, whereas the Core i7-860S Quad 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 Phenom II X4 and Core i7-860S Quad 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 Phenom II X4 has a 0.87 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. In this case, however, the difference is probably a good indicator that the is superior.

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 Phenom II X4 has a 1024 KB bigger L2 cache than the Core i7-860S Quad, but on the other hand, it is the Core i7-860S Quad that has a 2 MB bigger L3 cache than the Phenom II X4. In this case, the L2 size is probably what counts, so the Phenom II X4 is likely superior 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 Core i7-860S Quad has a 13 Watt lower Maximum TDP than the Phenom II X4 (though they were created with the same size 45 nm manufacturing technology). What this means is the Core i7-860S Quad will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewPhenom II X4 B65 is an unlocked Phenom II X2 565.

It should offer similar performance to a Phenom II X4 B99.
Core i7-860S Quad 2.53GHz is a power efficient CPU based on the 45nm, Nehalem architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 2.53GHz, which may go up to 3.46GHz and 8MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor DOES NOT integrated any graphics and has a rated board TDP of 82W.

It is a powerful Quad Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
