CPU Mini Review

Mini Review Core i7-880 Quad 3.06GHz is a high-end CPU based on the 45nm, Nehalem architecture. <br/> <br/> It offers 4 Physical Cores (8 Logical), initially clocked at 3.06GHz, which may go up to 3.73GHz and 8MB of L3 Cache. <br/> Among its many features, <b>HyperThreading, Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor DOES NOT integrated any graphics and has a rated board TDP of 95W. <br/> <br/> Its performance is very good and sufficient for any of today's games. The Celeron brand has been used by Intel for several distinct ranges of x86 CPUs targeted at budget personal computers. Celeron processors can run all IA-32 computer programs, but their performance is somewhat lower when compared to similar CPUs with higher-priced Intel CPU brands. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. These missing features have had a variable impact on performance. In some cases, the effect was significant and in other cases the differences were relatively minor. Many of the Celeron designs have achieved a very high bang for the buck, while at other times, the performance difference has been noticeable. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i7-880 Quad 3.06GHz is massively better than the Intel Celeron E3400 Dual-Core 2.6GHz 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 Core i7-880 Quad 3.06GHz and the Celeron E3400 Dual-Core 2.6GHz were released at the same time, so are likely to be quite similar.

The 4 has 2 more cores than the Celeron E3400 Dual-Core. { With 4 cores, the 4 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Core i7-880 Quad and Celeron E3400 Dual-Core 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 Core i7-880 Quad has a 0.46 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 4.

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 Core i7-880 Quad and the Celeron E3400 Dual-Core have the same L2 cache size, but the Celeron E3400 Dual-Core does not appear to have an L3 cache, so the Core i7-880 Quad definitely wins out in this area.

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.
