In terms of overall gaming performance, the AMD Sempron 3400+ is marginally better than the AMD Athlon XP 1700+ 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 Sempron 3400+ was released over three years more recently than the Athlon XP 1700+, and so the Sempron 3400+ is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Athlon XP 1700+ when running the latest games.

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 Sempron 3400+ and the Athlon XP 1700+ 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, the Sempron 3400+ and the Athlon XP 1700+ 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 Sempron 3400+ and Athlon XP 1700+ 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 Sempron 3400+ has a 0.34 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 Athlon XP 1700+ has a 128 KB bigger L2 cache than the Sempron 3400+, but neither of the CPUs have L3 caches, so the Athlon XP 1700+ 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 Sempron 3400+ has a 5 Watt lower Maximum TDP than the Athlon XP 1700+, and was created with a 90 nm smaller manufacturing technology. What this means is the Sempron 3400+ will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewSempron 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.The 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.
