In terms of overall gaming performance, the Intel Celeron G540T 2.1GHz is very slightly 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 Celeron G540T 2.1GHz was released over three years more recently than the Pentium Dual Core, and so the Celeron G540T 2.1GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Pentium Dual Core when running the latest games.

The Celeron G540T 2.1GHz and the Pentium Dual 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 Celeron G540T 2.1GHz and the Pentium Dual Core 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 Celeron G540T 2.1GHz and Pentium Dual 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 Pentium Dual Core has a 0.3 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. As such, we need to look elsewhere for more reliable comparisons.

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 Pentium Dual Core has a 512 KB bigger L2 cache than the Celeron G540T 2.1GHz, and although the Pentium Dual Core does not appear to have an L3 cache, its larger L2 cache means that it wins out in this area.

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 Celeron G540T 2.1GHz has a 30 Watt lower Maximum TDP than the Pentium Dual Core, and was created with a 33 nm smaller manufacturing technology. What this means is the Celeron G540T 2.1GHz will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewCeleron G540T Dual-Core 2.1GHz is a budget CPU based on the 32nm Sandy Bridge micro-architecture with many of its features disabled, including Turbo Boost and Hyper Threading, that is optimized for low power consumption.
It offers 2 Cores, clocked at 2.1GHz and integrated graphics clocked at 650MHz (1.0GHz in Turbo Mode) and the memory controller supports DDR3-1066. It's expected to consume up to 35 Watt and offers 2MB of L3 Cache.
Expect average gaming performance which should be sufficient for most demanding games. However, this CPU will become a bottleneck for any of today's high-end GPUs.
The 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.
