In terms of overall gaming performance, the AMD Athlon 5050e Dual Core is noticeably better than the Intel Pentium D 840 3.2GHz 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 over three years more recently than the Pentium D 840, and so the Athlon 5050e Dual is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Pentium D 840 when running the latest games.

The Athlon 5050e Dual and the Pentium D 840 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 Athlon 5050e Dual and the Pentium D 840 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 Athlon 5050e Dual and Pentium D 840 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 D 840 has a 0.6 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 Pentium D 840 has a 1024 KB bigger L2 cache than the Athlon 5050e Dual, but neither of the CPUs have L3 caches, so the Pentium D 840 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.

The Athlon 5050e Dual has a 85 Watt lower Maximum TDP than the Pentium D 840, and was created with a 25 nm smaller manufacturing technology. What this means is the Athlon 5050e Dual 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 ReviewOn 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.In April 2005, Intel's biggest rival, AMD, had x86 dual-core microprocessors intended for workstations and servers on the market, and was poised to launch a comparable product intended for desktop computers. As a response, Intel developed Smithfield, the first x86 dual-core microprocessor intended for desktop computers, beating AMD's Athlon 64 X2 by a few weeks. Intel first launched Smithfield on April 16, 2005 in the form of the 3.2 GHz Hyper-threading enabled Pentium Extreme Edition 840. On May 26, 2005, Intel launched the mainstream Pentium D branded processor lineup with initial clock speeds of 2.8, 3.0, and 3.2 GHz with model numbers of 820, 830, and 840 respectively. In March 2006, Intel launched the last Smithfield processor, the entry-level Pentium D 805, clocked at 2.66 GHz with a 533 MT/s bus. The relatively cheap 805 was found to be highly overclockable; 3.5 GHz was often possible with good air cooling. Running it at over 4 GHz was possible with water cooling, and at this speed the 805 outperformed the top-of-the-line processors (May 2006) from both major CPU manufacturers (the AMD Athlon 64 FX-60 and Intel Pentium Extreme Edition 965) in many benchmarks including power consumption.
