In terms of overall gaming performance, the Intel Celeron 1000M 1.8GHz is noticeably better than the Intel Celeron Dual-Core 867 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 1000M 1.8GHz was released over a year more recently than the Celeron Dual-Core 867, and so the Celeron 1000M 1.8GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The Celeron 1000M 1.8GHz and the Celeron Dual-Core 867 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 Celeron 1000M 1.8GHz and the Celeron Dual-Core 867 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 Celeron 1000M 1.8GHz and Celeron Dual-Core 867 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 Celeron 1000M 1.8GHz has a 0.5 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 Celeron 1000M 1.8GHz and the Celeron Dual-Core 867 have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, we have to look back to the clock rate, where the Celeron 1000M 1.8GHz wins out.

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 Celeron Dual-Core 867 has a 18 Watt lower Maximum TDP than the Celeron 1000M 1.8GHz. However, the Celeron 1000M 1.8GHz was created with a 10 nm smaller manufacturing technology. Overall, by taking both into account, the Celeron 1000M 1.8GHz is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

CPU Mini Review

Mini ReviewCeleron 1000M 1.8GHz is a budget laptop CPU based on the Ivy Bridge micro-architecture.
Manufactured with a 22nm technology, it features 2 Cores clocked at 1.8GHz and Integrated Graphics initially clocked at 650MHz and that go up to 1000MHz in Turbo Mode. The Memory controller supports up to DDR3-1600 memory type. The Max power drawn should be of around 35W.
Its performance is reasonable but will become a bottleneck for mainstream Graphics Cards.
Sandy 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.
