CPU Mini Review

Mini Review 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. Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.<br /> The Core microarchitecture returned to lower clock rates and improved the usage of both available clock cycles and power when compared with the preceding NetBurst microarchitecture of the Pentium 4/D-branded CPUs. The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs while increasing their processing capacity. Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core 2 Duo L7300 1.4GHz is very slightly better than the Intel Celeron M 410 1.46GHz 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 M 410 1.46GHz and the Core 2 Duo L7300 1.4GHz were released at the same time, so are likely to be quite similar.

The 2 has 1 more core than the Celeron M 410. However, while the 2 will probably perform better than the Celeron M 410, 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 M 410 and Core 2 Duo 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 M 410 has a 0.06 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 <span class='gpu2Mention'>Core 2 Duo</span> has a 3072 KB bigger L2 cache than the <span class='gpu1Mention'>Celeron M 410</span>, but neither of the CPUs have L3 caches, so the <span class='gpu2Mention'>Core 2 Duo</span> 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.
