In terms of overall gaming performance, the Intel Core 2 Extreme QX6850 3.0GHz is massively better than the AMD Opteron 2222 X2 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 Opteron 2222 X2 was released less than a year after the Core 2 Extreme, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core 2 Extreme has 2 more cores than the Opteron 2222 X2. With 4 cores, the Core 2 Extreme is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Opteron 2222 X2 and Core 2 Extreme 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 Opteron 2222 X2 and the Core 2 Extreme both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 Core 2 Extreme has a 6144 KB bigger L2 cache than the Opteron 2222 X2, but neither of the CPUs have L3 caches, so the Core 2 Extreme 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.

The Opteron 2222 X2 has a 35 Watt lower Maximum TDP than the Core 2 Extreme. However, the Core 2 Extreme was created with a 25 nm smaller manufacturing technology. Overall, by taking both into account, the Core 2 Extreme is likely the CPU with the lower heat production and power requirements, by a small amount.

CPU Mini Review

Mini ReviewFor Socket F and Socket AM2 Opterons, each chip has a four-digit model number, in the form Opteron XZYY. For all Opterons, the first digit (the X) specifies the number of CPUs on the target machine:
1 - Designed for uniprocessor systems
2 - Designed for dual-processor systems
8 - Designed for systems with 4 or 8 processors
For Socket F and Socket AM2 Opterons, the second digit (the Z) represents the processor generation. Presently, only 2 (dual-core), DDR2, 3 (quad-core) and 4 (six-core) are used.
For all Opterons, the last two digits in the model number (the YY) indicate the clock frequency of a CPU, a higher number indicating a higher clock frequency. This speed indication is comparable to processors of the same generation if they have the same amount of cores, single-cores and dual-cores have different indications despite sometimes having the same clock frequency.
The suffix HE or EE indicates a high-efficiency/energy-efficiency model having a lower TDP than a standard Opteron. The suffix SE indicates a top-of-the-line model having a higher TDP than a standard Opteron.
Core 2 Extreme QX6850 3.0GHz is a performance Processor based on the 65nm Core micro-architecture.

It offers 4 Physical Cores (4 Logical), clocked at 3.0GHz and 8MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 130W.

It is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem.
