CPU Mini Review

Mini Review Intel Atom is the brand name for a line of ultra-low-voltage IA-32 and x86-64 CPUs (or microprocessors) from Intel, originally designed in 45 nm CMOS with subsequent models, codenamed Cedar, using a 32 nm process. Atom is mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, and mobile internet devices (MIDs). Yonah was the code name for (the core of) Intel's first generation of 65 nm process mobile microprocessors, based on the Banias/Dothan-core Pentium M microarchitecture. SIMD performance has been improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations, while integer performance decreased slightly due to higher latency cache. Additionally, Yonah includes support for the NX bit.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core Solo U1400 1.2GHz is marginally better than the Intel Atom Z600 0.8GHz 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 Atom Z600 0.8GHz and the Core Solo U1400 1.2GHz were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful CPUs. Neither of these will be able to run the latest games in any playable way.

{ The Atom Z600 0.8GHz and the Core Solo U1400 both have 1 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, theAtom Z600 0.8GHz and the Core Solo U1400 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 Atom Z600 0.8GHz and Core Solo U1400 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 Solo U1400 has a 0.4 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 <span class='gpu2Mention'>Core Solo U1400</span> has a 1536 KB bigger L2 cache than the <span class='gpu1Mention'>Atom Z600 0.8GHz</span>, but neither of the CPUs have L3 caches, so the <span class='gpu2Mention'>Core Solo U1400</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.
