In terms of overall gaming performance, the Intel Core i5-4302Y 1.6GHz 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 i5-4302Y 1.6GHz was released over three years more recently than the Core i7-620UE 2-Core, and so the Core i5-4302Y 1.6GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i7-620UE 2-Core when running the latest games.

The Core i5-4302Y 1.6GHz 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 i5-4302Y 1.6GHz and the Core i7-620UE 2-Core may still be able to run slightly older games fairly effectively.

Both the Intel Core i5-4302Y 1.6GHz and the Intel Core i7-620UE 2-Core 1.06GHz have the same number of threads. Both the Core i5-4302Y 1.6GHz and the Core i7-620UE 2-Core use hyperthreading. The Core i5-4302Y 1.6GHz 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 i5-4302Y 1.6GHz and Core i7-620UE 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 Core i5-4302Y 1.6GHz has a 0.54 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 enough that it possibly indicates the superiority of the .

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 i5-4302Y 1.6GHz and the Core i7-620UE 2-Core 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 i5-4302Y 1.6GHz.

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 i5-4302Y 1.6GHz has a 6 Watt lower Maximum TDP than the Core i7-620UE 2-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Core i5-4302Y 1.6GHz 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 i5-4302Y is an energy efficient dual core processor clocked at 1.6 GHz and can go up to 2.3 GHz using turbo boost under extreme loads. It has an extremely low TDP of 11.5 watts.It equips an HD 4400 iGPU with 200 MHz base clock and 850 MHz turbo boost clock It's performance is average and only suited for non-demanding applications and games.Core 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.
