CPU Mini Review

Mini Review Turion II Ultra (codenamed Caspian) is the mobile version of the K10.5 architecture produced using 45 nm fabrication process, also known by its desktop variant Regor. It is a dual core processor, and features clock speeds of 2.4 GHz to 2.7 GHz, 2 MB total L2 cache (1 MB per core), HyperTransport at 3.6 GT/s, and a 128 bit FPU. It maintains a TDP of 35W from its predecessor Turion X2 Ultra (codenamed Griffin). Core i5-520UM 1.06GHz is a super energy efficient mobile processor based on the 32nm, Nehalem architecture. <br/> <br/> It offers 2 Physical Cores (4 Logical), initially clocked at 1.066GHz, which may go up to 1.866GHz and 3MB of L3 Cache. <br/> Among its many features, <b>Turbo Boost and Virtualization</b> are activated. <br/> <br/> The processor integrates very weak Graphics called <b>Intel i5 520UM</b>, with 12 Execution Units, initially clocked at 166MHz which go up to 500MHz, in Turbo Mode and share the L2 Cache and system RAM with the processor. <br/> Both the processor and integrated graphics have a rated board TDP of 18W. <br/> <br/> Its performance is below the average and so most demanding games will not run optimally.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Core i5-520UM 1.06GHz is noticeably better than the AMD Turion II Ultra Dual-Core Mobile M600 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 Turion II Ultra Dual-Core Mobile M600 and the Core i5-520UM 1.06GHz were released at the same time, so are likely to be quite similar.

{ The Turion II Ultra and the Core i5-520UM 1.06GHz 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, theTurion II Ultra and the Core i5-520UM 1.06GHz 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 Turion II Ultra and Core i5-520UM 1.06GHz 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 Turion II Ultra has a 1.334 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 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='gpu1Mention'>Turion II Ultra</span> has a 1536 KB bigger L2 cache than the <span class='gpu2Mention'>Core i5-520UM 1.06GHz</span>, and although the Turion II Ultra 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.
