In terms of overall gaming performance, the Intel Core i3-2312M 2.1GHz 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 i3-2312M 2.1GHz 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 i3-2312M 2.1GHz 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 i3-2312M 2.1GHz 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 Core i3-2312M 2.1GHz 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 Core i3-2312M 2.1GHz has a 1.04 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 Core i7-620UE 2-Core and the Core i3-2312M 2.1GHz 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 i3-2312M 2.1GHz.

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 i3-2312M 2.1GHz (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).

The Core i3-2312M 2.1GHz has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Core i7-620UE 2-Core, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

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.
Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.Originally, implementations targeted a 32 nanometer manufacturing process based on planar double-gate transistors. Subsequent products, codenamed Ivy Bridge, use a 22 nanometer process. The Ivy Bridge die shrink, known in the Intel Tick-Tock model as the "tick", is based on 3D tri-gate transistors. Intel demonstrated Ivy Bridge processors in 2011.
