In terms of overall gaming performance, the AMD Athlon 5050e Dual Core is noticeably better than the AMD Athlon LE-1660 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 Athlon 5050e Dual was released less than a year after the Athlon LE-1660, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Athlon 5050e Dual has 1 more core than the Athlon LE-1660. However, while the Athlon 5050e Dual will probably perform better than the Athlon LE-1660, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. This should not affect games that are a few years old, and even the latest games should at least be playable on very low settings, as only recently have game developers begun to harness the power of multiple cores.

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 Athlon LE-1660 and Athlon 5050e Dual 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 Athlon LE-1660 has a 0.2 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 Athlon 5050e Dual has a 512 KB bigger L2 cache than the Athlon LE-1660, but neither of the CPUs have L3 caches, so the Athlon 5050e Dual 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 Athlon LE-1660 and the Athlon 5050e Dual have the same TDP of 45 Watts, and were created with the same manufacturing size of 65 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewThe Athlon made its debut on June 23, 1999. Athlon is the ancient Greek word for Champion/trophy of the games.
Athlon is the brand name applied to a series of x86-compatible microprocessors designed and manufactured by Advanced Micro Devices (AMD). The original Athlon (now called Athlon Classic) was the first seventh-generation x86 processor and retained the initial performance lead it had over Intel's competing processors for a significant period of time. The original Athlon also had the distinction of being the first desktop processor to reach speeds of one gigahertz (GHz). AMD has continued using the Athlon name with the Athlon 64, an eighth-generation processor featuring x86-64 (later renamed AMD64) architecture, and the Athlon II.
On April 21, 2005, less than a week after the release of Venice and San Diego, AMD announced its next addition to the Athlon 64 line, the Athlon 64 X2. Released on May 31, 2005, it also initially had two different core revisions available to the public, Manchester and Toledo, the only appreciable difference between them being the amount of L2 cache. Both were released only for Socket 939. The Athlon 64 X2 was received very well by reviewers and the general public, with a general consensus emerging that AMD's implementation of multi-core was superior to that of the competing Pentium D. Some felt initially that the X2 would cause market confusion with regard to price points since the new processor was targeted at the same enthusiast, US$350 and above market already occupied by AMD's existing socket 939 Athlon 64s. AMD's official breakdown of the chips placed the Athlon X2 aimed at a segment they called the prosumer, along with digital media fans. The Athlon 64 was targeted at the mainstream consumer, and the Athlon FX at gamers.
