In terms of overall gaming performance, the Intel Atom D2550 1.87GHz is very slightly better than the AMD Sempron Mobile 3300+ 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 Atom D2550 1.87GHz was released over three years more recently than the Sempron Mobile 3300+, and so the Atom D2550 1.87GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Sempron Mobile 3300+ when running the latest games.

The Atom D2550 1.87GHz has 1 more core than the Sempron Mobile 3300+. However, while the Atom D2550 1.87GHz will probably perform better than the Sempron Mobile 3300+, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

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 Atom D2550 1.87GHz and Sempron Mobile 3300+ 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 Mobile 3300+ has a 0.14 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 Sempron Mobile 3300+ has a 127 KB bigger L2 cache than the Atom D2550 1.87GHz, but neither of the CPUs have L3 caches, so the Sempron Mobile 3300+ 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 Atom D2550 1.87GHz has a 52 Watt lower Maximum TDP than the Sempron Mobile 3300+, and was created with a 58 nm smaller manufacturing technology. What this means is the Atom D2550 1.87GHz 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 ReviewThis Atom CPU is one of the dual core releases, that's also hyper-threaded! But still, with only 2 x 512 kB 8-way associative caches and a clock speed @ 1.86 GHz, don't expect too much from it.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.
