Intel Core i7 920 and 965 XE CPU Review

CPU by piotke @ 2008-11-03

In a few weeks you can find a brand new Intel CPU at your local hardware shop, it still carries the Core name but it is drastically different compared to their previous Core 2 units. The Core i7 has an onboard memory controller and hyperthreading is re-introduced. We compare the performance of the entry level 920 model as well as the high end 965 XE.

Test Configurations

On the follow pages we'll run a variety of tests, grouped in the following categories:
  • Single Core (Benchmarks that use only one core, such as Superpi, Hexus Pifast, ..)
  • Multi Core (Benchmarks that use obviouly, more then one core, such as Wprime, Cinebench, ...)
  • 3D and gaming (The Futuremark suite and a few games)


I started benching at first on and Microsoft Windows Vista 64 bit. But even with the latest drivers, I had nothing but trouble. That's why I choose to go for a more proven platform, and went with and Microsoft Windows XP 32 Bit SP3. Downside of this is that I couldn't run some benchmarks, such as Vantage.

We used a few platforms, because of the different sockets and memory requirements. Here they are:


Test Setup Core 2 Duo
CPU Intel Core 2 Duo E8600 (@ 3.33 Ghz)

CPU Arithmetic Benchmark

The following benchmark is multi threaded. The 4 real cores and the 4 virtual cores, together 8 threads are working nicely together as you can see.

Score, higher is better


CPU Multimedia Benchmark

Same goes for the Multimedia CPU benchmark.

Score, higher is better


Memory Bandwidth Benchmark

The triple channel memory configuration seems to be paying off. Close to 16 gigabyte of bandwidth. The i7 920 is performing a bit lower, but keep in mind that the memory is running 266 MHz slower compared to the i7 965 XE. The Core 2 Duo configuration is getting nowhere near. And AMD is in the middle, but not close enough to threaten the new Intel series.
