In terms of overall gaming performance, the Intel Core i7-660UM 2-Core 1.33GHz is significantly better than the AMD Athlon II N370 Dual-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.

The Athlon II N370 was released less than a year after the Core i7-660UM 2-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Athlon II N370 and the Core i7-660UM 2-Core both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the Athlon II N370 and the Core i7-660UM 2-Core may still be able to run slightly older games fairly effectively.

The Core i7-660UM 2-Core has 2 more threads than the Athlon II N370. The Athlon II N370 has one thread per physical core, whereas the Core i7-660UM 2-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 Athlon II N370 and Core i7-660UM 2-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 Athlon II N370 has a 1.17 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 Athlon II N370 has a 512 KB bigger L2 cache than the Core i7-660UM 2-Core, and although the Athlon II N370 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 Core i7-660UM 2-Core has a 17 Watt lower Maximum TDP than the Athlon II N370, and was created with a 13 nm smaller manufacturing technology. What this means is the Core i7-660UM 2-Core 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 ReviewThe AMD Athlon II Dual-Core Mobile M360 is an entry level Dual Core CPU by AMD for laptops with an integrated dual channel DDR2 memory controller (400MHz). The core was named Caspian and based on the K10 architecture.
The Athlon II series has the advantage of Virtualisation and 64-bit processing support
Core i7-660UM 2-Core 1.33GHz is an ultra energy efficient mobile CPU based on the 32nm, Nehalem architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 1.33GHz, which may go up to 2.4GHz and 4MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates very weak Graphics called Intel HD i7 660UM, with 10 Execution Units, initially clocked at 166MHz and that go up to 500MHz, 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 18W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
