CPU Mini Review

Mini Review 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. The last generation of Pentium D branded processors was Presler identified by the product code 80553, and made of two 65 nm-process cores found also in Pentium 4 branded Cedar Mill CPUs. Presler introduced the 'multi-chip module, or MCM, which consisted of two single-core dies placed next to each other on the same substrate package. This allowed Intel to produce these processors at a reduced production cost as a result of higher yields. Presler was supported by the same chipsets as Smithfield. It was produced using 65 nm technology similar to Yonah. Presler communicated with the system using an 800 MT/s FSB, and its two cores communicated also using the FSB, just as in Smithfield. Presler also included Intel VT-x (formerly Vanderpool) –although this was limited to the 9x0 models, and not in the 9x5 models– Intel 64, XD bit, and EIST (Enhanced Intel SpeedStep Technology). Presler was released in the first quarter of 2006 with a 2x2 MB Level 2 cache. Its models included 915, 920, 925, 930, 935, 940, 945, 950 and 960 (with a respective 2.8, 2.8, 3.0, 3,0, 3.2, 3.2, 3.4, 3.4, and 3.6 GHz clock frequency).

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Celeron G465 1.9GHz is very slightly better than the Intel Pentium D 960 3.6GHz 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 Celeron G465 1.9GHz and the Pentium D 960 3.6GHz were released at the same time, so are likely to be quite similar.

The 2 has 1 more core than the Celeron G465 1.9GHz. However, while the 2 will probably perform better than the Celeron G465 1.9GHz, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. This should not affect games that are a few years old, and even the latest games should at least be playable on very low settings, as only recently have game developers begun to harness the power of multiple cores.

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 G465 1.9GHz and Pentium D 960 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 Pentium D 960 has a 1.7 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 probably a good indicator that the 2 is superior.

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 <span class='gpu2Mention'>Pentium D 960</span> has a 3840 KB bigger L2 cache than the <span class='gpu1Mention'>Celeron G465 1.9GHz</span>, and although the Pentium D 960 does not appear to have an L3 cache, its larger L2 cache means that it 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.
