CPU Mini Review

Mini Review The Athlon made its debut on June 23, 1999. Athlon is the ancient Greek word for Champion/trophy of the games. <br />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. Sempron has been the marketing name used by AMD for several different budget desktop CPUs, using several different technologies and CPU socket formats. The Sempron replaced the AMD Duron processor and competes against Intel's Celeron series of processors. AMD coined the name from the Latin semper, which means always, to suggest the Sempron is suitable for daily use, practical, and part of everyday life.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Sempron 2800+ is marginally better than the AMD Athlon MP 1900+ 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.

Both the Athlon MP 1900+ and the Sempron 2800+ were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful CPUs. Neither of these will be able to run the latest games in any playable way.

{ The Athlon MP 1900+ and the Sempron 2800+ both have 1 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, theAthlon MP 1900+ and the Sempron 2800+ 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 MP 1900+ and Sempron 2800+ 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 MP 1900+ and the Sempron 2800+ both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 MP 1900+ and the Sempron 2800+ have the same L2 cache size, and neither CPU appears to have an L3 cache. They even have the same L1 cache size, so are identical in terms of cache size.

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.
