In terms of overall gaming performance, the Intel Pentium Dual Core E6600 3.06GHz is noticeably better than the Intel Pentium Dual Core E2220 2.40GHz 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 E6600 3.06GHz was released less than a year after the E2220 2.40GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The E2220 2.40GHz and the E6600 3.06GHz 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 E2220 2.40GHz and the E6600 3.06GHz 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 E2220 2.40GHz and E6600 3.06GHz 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 E6600 3.06GHz has a 0.66 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 E6600 3.06GHz has a 1024 KB bigger L2 cache than the E2220 2.40GHz, but neither of the CPUs have L3 caches, so the E6600 3.06GHz wins out in this area with its larger L2 cache.

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 E2220 2.40GHz and the E6600 3.06GHz have the same TDP of 65 Watts, but the E6600 3.06GHz has a lower lithography size, and so will affect your yearly electricity bills less adversely.

CPU Mini Review

Mini ReviewThe Intel Pentium Dual-Core brand refers to mainstream x86-architecture microprocessors from Intel. With the exception of a few early Yonah based mobile models, they are now all based on the 64-bit Core microarchitecture. Pentium Dual-Core lacks the SSE4.1 instruction found in the 45 nm Core 2 processors.The Pentium Dual-Core brand was used for mainstream x86-architecture microprocessors from Intel from 2006 to 2009 when it was renamed to Pentium. The processors are based on either the 32-bit Yonah or (with quite different microarchitectures) 64-bit Merom-2M, Allendale, and Wolfdale-3M core, targeted at mobile or desktop computers.
In terms of features, price and performance at a given clock frequency, Pentium Dual-Core processors were positioned above Celeron but below Core and Core 2 microprocessors in Intel's product range. The Pentium Dual-Core was also a very popular choice for overclocking, as it can deliver optimal performance (when overclocked) at a low price.
