In terms of overall gaming performance, the Intel Core i3-M390 2.67GHz is marginally better than the Intel Core i7-620UE 2-Core 1.06GHz 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 Core i3-M390 2.67GHz was released less than a year after the Core i7-620UE 2-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i7-620UE 2-Core and the Core i3-M390 2.67GHz 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 i7-620UE 2-Core and the Core i3-M390 2.67GHz may still be able to run slightly older games fairly effectively.

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 i7-620UE 2-Core and the Core i3-M390 2.67GHz 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 1.61 GHz faster base clock rate, the Core i3-M390 2.67GHz manages to provide massively better performance than the Core i7-620UE 2-Core.

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 i7-620UE 2-Core and the Core i3-M390 2.67GHz have the same L2 cache size, but the Core i7-620UE 2-Core has a 1 MB bigger L3 cache, so in this area, it wins out over the Core i3-M390 2.67GHz.

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 i7-620UE 2-Core has a 17 Watt lower Maximum TDP than the Core i3-M390 2.67GHz (though they were created with the same size 32 nm manufacturing technology). What this means is the Core i7-620UE 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 ReviewCore i7-620UE 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 620UE, 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.
The Core i3 was intended to be the new low end of the performance processor line from Intel, following the retirement of the Core 2 brand.
The first Core i3 processors were launched on January 7, 2010.
The first Nehalem based Core i3 was Clarkdale-based, with an integrated GPU and two cores.[20] The same processor is also available as Core i5 and Pentium, with slightly different configurations.
The Core i3-3xxM processors are based on Arrandale, the mobile version of the Clarkdale desktop processor. They are similar to the Core i5-4xx series but running at lower clock speeds and without Turbo Boost.
