In terms of overall gaming performance, the Intel Xeon Processor X3380 is very slightly better than the Intel Core 2 Quad Q9400 2.66GHz 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 Xeon Processor X3380 was released less than a year after the Core 2 Quad, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Xeon Processor X3380 and the Core 2 Quad both have 4 cores, which is not likely to be a limiting factor for gaming.

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 Xeon Processor X3380 and the Core 2 Quad are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.5 GHz faster base clock rate, the Xeon Processor X3380 manages to provide noticeably better performance than the Core 2 Quad.

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 Xeon Processor X3380 has a 6144 KB bigger L2 cache than the Core 2 Quad, but neither of the CPUs have L3 caches, so the Xeon Processor X3380 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 Xeon Processor X3380 and the Core 2 Quad have the same TDP of 95 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 ReviewXeon Processor X3380 is a server CPU based on thr 45nm, Yorkfield architecture.
It's therefore related to the Core 2 Quad Series. It offers 4 Cores, each clocked at 3.167GHz and 12MB of L2 Cache. Most of the architectural features are enabled - including the low power features.
Both its performance and price are high and so gamers are still better of getting any Core 2 Quad, over this CPU which is not meant for gaming purposes.
Core 2 Quad Q9400 2.66GHz is a high-end Processor based on the 45nm Core micro-architecture.

It offers 4 Physical Cores (4 Logical), clocked at 2.66GHz and 6MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 95W.

It offers average performance. It will therefore become a bottleneck in today's demanding games.
