In terms of overall gaming performance, the Core i7-620UM 2-Core and the Core i7-620UE 2-Core are equal when it comes to running the latest games. This means they will be about the same in terms of bottlenecking (or not bottlenecking) GPUs.

Both the Core i7-620UM 2-Core 1.06GHz and the Core i7-620UE 2-Core 1.06GHz were released at the same time, so are likely to be quite similar.

The Core i7-620UM 2-Core and the Core i7-620UE 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 Core i7-620UM 2-Core and the Core i7-620UE 2-Core may still be able to run slightly older games fairly effectively.

Both the Intel Core i7-620UM 2-Core 1.06GHz and the Intel Core i7-620UE 2-Core 1.06GHz have the same number of threads. Both the Core i7-620UM 2-Core and the Core i7-620UE 2-Core use hyperthreading. The Core i7-620UM 2-Core has 2 logical threads per physical core and the Core i7-620UE 2-Core has 2.

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 Core i7-620UM 2-Core and the Core i7-620UE 2-Core are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.0069999999999999 GHz faster base clock rate, the Core i7-620UM 2-Core manages to provide marginally better performance than the Core i7-620UE 2-Core. However, the manages to eke GHz higher frequency when being stressed.

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 Core i7-620UM 2-Core and the Core i7-620UE 2-Core have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, we have to look back to the clock rate, where the Core i7-620UM 2-Core wins out.

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.

Both the Core i7-620UM 2-Core and the Core i7-620UE 2-Core have the same TDP of 18 Watts, and were created with the same manufacturing size of 32 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewCore i7-620UM 2-Core 1.06GHz is an ultra energy efficient mobile CPU based on the 32nm, Nehalem architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 1.067GHz, which may go up to 2.133GHz 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 620UM, 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.

Its performance is below the average and so most demanding games will not run optimally.
