In terms of overall gaming performance, the Intel Core 2 Duo P9600 2.66GHz is noticeably better than the AMD Turion II Dual-Core Mobile P520 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.

The Turion II Dual-Core was released over a year more recently than the Core 2 Duo, and so the Turion II Dual-Core is likely to have better levels of support, and will be more optimized for running the latest games.

The Turion II Dual-Core and the Core 2 Duo 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, the Turion II Dual-Core and the Core 2 Duo 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 Dual-Core 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 Core 2 Duo has a 0.36 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 Core 2 Duo has a 4096 KB bigger L2 cache than the Turion II Dual-Core, but neither of the CPUs have L3 caches, so the Core 2 Duo 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.

Both the Turion II Dual-Core and the Core 2 Duo have the same TDP of 25 Watts, and were created with the same manufacturing size of 45 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewTurion 64 X2 is AMD's 64-bit dual-core mobile CPU, intended to compete with Intel's Core and Core 2 CPUs. The Turion 64 X2 was launched on May 17, 2006, after several delays. These processors use Socket S1, and feature DDR2 memory. They also include AMD Virtualization Technology and more power-saving features. AMD first produced the Turion 64 X2 on IBM's 90 nm Silicon on insulator (SOI) process (cores with the Taylor codename). As of May 2007, they have switched to a 65 nm Silicon-Germanium stressed process[citation needed], which was recently achieved through the combined effort of IBM and AMD, with 40% improvement over comparable 65 nm processes. The earlier 90 nm devices were codenamed Taylor and Trinidad, while the newer 65 nm cores have codename Tyler.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.
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.
