In terms of overall gaming performance, the Intel Celeron Dual-Core 867 1.3GHz is noticeably better than the Intel Celeron M B787 1.3GHz 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 Celeron Dual-Core 867 was released less than a year after the Celeron M B787, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Celeron Dual-Core 867 has 1 more core than the Celeron M B787. However, while the Celeron Dual-Core 867 will probably perform better than the Celeron M B787, 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 Celeron Dual-Core 867 and the Celeron M B787 are from the same family of CPUs, and thus their clock speeds are directly comparable. That isn't particularly helpful, however, as the Celeron Dual-Core 867 and the Celeron M B787 provide identical clock rates and thus extremely similar performance.

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 Celeron Dual-Core 867 has a 256 KB bigger L2 cache than the Celeron M B787, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 Celeron Dual-Core 867 and the Celeron M B787 have the same TDP of 17 Watts, and were created with the same manufacturing size of 32 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewSandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.The Celeron is a family of microprocessors from Intel targeted at the low-end consumer market. CPUs in the Celeron brand have used designs from sixth- to eighth-generation CPU microarchitectures.
