In terms of overall gaming performance, the AMD Phenom II X2 X620 Black Edition 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.

The Phenom II X2 was released less than a year after the Turion II Ultra, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Phenom II X2 and the Turion II Ultra 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 Phenom II X2 and the Turion II Ultra 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 Phenom II X2 and Turion II Ultra 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 Phenom II X2 has a 0.7 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 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 Phenom II X2 and the Turion II Ultra have the same L2 cache size, and neither CPU appears to have an L3 cache. They even have the same L1 cache size, so are identical in terms of cache size.

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.

The Turion II Ultra has a 10 Watt lower Maximum TDP than the Phenom II X2 (though they were created with the same size 45 nm manufacturing technology). What this means is the Turion II Ultra will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewPhenom II X2 X620 Black Edition is a Dual core mobile CPU based on the Champlain Core and therefore related to the Athlon II X2 Desktop Series.
It features 2 cores, clocked 3.1GHz and the fastest supported memory is DDR3-1333.
Its performance is quite average and decent enough to run most games at high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require reduced settings to be played optimally.
It's worth mentioning this CPU has unlocked clock multiplier and therefore can be overclocked easily.
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).
