Introduction:
Do you remember when processors were so big and heavy that you had to lift them with both hands? Well luckily those days are long gone and as technology progresses, processors are slowly shrinking in size while increasing in performance. Over the last two years we have grown familiar with 65 nm processors that actually produce less heat and are more energy efficient than processors of the past . Now there is something new, the 45nm processor which can deliver greater performance and better power efficiency. So what CPU manufacturer is producing such a processor?
The Intel Core 2 Extreme quad-core QX9650 processor is one of Intel’s first 45nm processors to utilize hafnium-infused circuitry to deliver greater performance and more power efficiency. The Intel Core 2 Extreme quad-core QX9650 also runs at 3.0 GHz and has 12mb of L2 cache and a front side bus of 1333 MHz, something that should make any enthusiasts mouth water. Since the introduction of quad-core processors Intel has been a leader in innovative technology but will the latest technology used in the Intel Core 2 Extreme quad-core QX9650 be worthy?
Closer Look:
Our Core 2 Extreme QX9650 was shipped directly from Intel so it was packaged in a black static proof box. The inside of the box is lined with both pink and black foam to protect the processor.
The QX9650 looks no different than any other LGA 775 chip but its what's under the hood that should make the difference.
Installation:
To install the Intel Core 2 Extreme quad-core processor, you will first need a motherboard that is compatible with the CPU. Whether it be through a bios flash or a motherboard that is designed to support it is of extreme importance. As you can see, I first chose to use the Abit IP35 motherboard which I thought was compatible with the processor, but I was mistaken and later found that at this time, only the Abit IP35 Pro support it. I then tried my DFI Lanpaty 680i LT, but ended up crushing the resistors on the rear of the board installing the Thermalright Ultra90 heatsink. So finally with a bios flash, I was able to utilize my DFI Lanparty UT P35-T2R.
If your motherboard needs a bios flash in order to run the QX9650, I would suggest flashing the bios prior to installing the processor, all three boards (Abit IP35 not supported) would not even post prior to a bios flash. I had originally chose to use the Thermalright Ultra 90 heatsink on the DFI motherboards because of their preinstalled NB heatsinks. My Zerotherm fan without a mod will not mount unless the fan itself is facing upwards, but since I had already crushed the resistors on one DFI board with the rear plate of the Ultra 90, I decided to use the Zerotherm heatsink facing upward. It comes with an X bracket where the other has an oblong bracket.

- Resolution: 2750x2048
- Quality: 500
- Limit Memory use: 512MB
The measurement used is time to render, in minutes, to complete.

We are now benchmarking with Cinebench 10, where values are marked higher than Cinebench 9, due to changes in how it reads the multicore CPUs.
Testing:
Now that the system benchmarks are complete, we will move on to the video benchmarking portion of the review. We will be using an assortment of games to test performance across different processors to look for any performance advantages. The testing will start with resolutions at 800x600 and progressing to 1280x1024 to try and take the video card out of the equation and show the performance at resolutions where processor performance can influence the results.
The game tests that we use are as follows:
- Far Cry
- F.E.A.R.
- Quake 4
- Call of Duty 2
- Flight Simulator X
- Need For Speed: Most Wanted
- 3D Mark06
- RyderMark
First up we have Far Cry. This game makes extensive use of pixel shaders and features Polybump Normal Mapping technology to increase character details.
We will be using the Hardware OC Benchmarking Utility version 1.8 with the following settings.
- Maximum quality option, Direct3D renderer
- Level: Volcano, demo: Volcano.tmd
- Pixel shader: model 2.0b
- Anti-aliasing: 4×
- Anisotropic filtering: 8×
- HDR: disabled
- Geometry Instancing: disabled
- Normal-maps compression: disabled
In older games such as Far Cry, lower resolutions are where the CPU is a factor as you can see at the resolution of 800 x 600 the overclocked frame rates almost peaked 400 FPS. With the release of newer DirectX 10 games which are made for multi-core processors we should start to see higher frame rates in higher resolutions with the CPU giving the video card a boost. In the past as you crept into the higher resolutions the CPU was taken out of the equation leaving most of the work to the video card.
Testing:
F.E.A.R. is a newer game that includes its own benchmarking utility. We will be using this test to benchmark the game. This game introduces a new AI model that emulates real squad behavior. It has the ability to counteract the moves you make rather than having a predictable routine.
The settings we will use are below:
- FSAA: x4
- Anisotropic: x16
- Effects: Max
- Computer: High
- Soft Shadow: Off
Testing:
Quake 4 is next up for testing. We will be using the Hardware OC Quake 4 Benchmark Utility version 1.5 to complete the testing with this game. You will need to update to the most current version for the latest time demo and bug fixes. Average FPS (frames per second) will be the measure used.
The settings we will use are listed below:
- IDsoft Demo
- Quality: High
- Aspect Ratio: [4:3]
- Anti-aliasing: 4×
- Anisotropic filtering: 4x
- Symmetric Multi-Processing (SMP) enabled
Testing:
Call of Duty 2 is a WWII first-person shooter game that is dated, but still maintains a tremendous online following. This test will consist of a timed run on the Stalingrad multi-player map, measured by Average FPS (frames per second).
The settings used are listed below:
- Anti-aliasing: x4
- Texture Filter: Trilinear
Testing:
Benchmark: BioShock
BioShock is an interesting new first person shooter that has recently hit the market. This title poses quite a challenge for video cards.
Settings:
- All settings to Maximum
After looking at the last four benchmarks you will notice that even overclocked at 1024x768 when the CPU becomes less of a factor, the FPS are virtually the same.
Testing:
Need For Speed: Most Wanted. For this test, we will time each race and record the average FPS (Frames Per Second) achieved.
The settings we will use are listed below.
- All settings at 3/4 of highest performance
- Tests in 3 different resolutions
Testing:
3DMark06 is one of the benchmarks that always comes up when a bragging contest begins. 3DMark06 presents a severe test for many of today's hardware components. Let's see how this set of processors perform. We will only be comparing the E6700, E6750 and AMD 6000+ for this series of benchmarks. The settings used are listed below.
Settings:
- SM2.0 Graphics Tests: GT1- Return to Proxycon, GT2- Firefly Forest
- CPU Tests: Cpu1- Red Valley, CPU2- Red Valley
- HDR/SM3.0 Graphics Tests: HDR1- Canyon Flight, HDR2- Deep Freeze
Because this review is all about the processor, we will be showing how the CPU scored in each of the resolutions we tested.

Overclocking:
I just might not ever use another DFI board again. After spending days overclocking testing for stability and making sure I had the perfect settings my DFI Lanparty UT P35-T2R decided it wasn’t going to work at all. I beg
