E6420 VS E6400

I've been looking for benchmarks for the new E6420 but I'm not finding much. I've basically wondering what the performance difference is between the two chips. I currently have the E6400 so I'm wondering if it would be worth swapping to the E6420.

Any insights?

as you can see the difference in cpu score is very small, 4mb might be a little more usefull if you encode videos or use rendering apps. and no, if you already got e6400 i don't think it's worth it to upgrade to e6420, in my opinion.

Yeah that's hardly worth looking at except that the e6420 is cheaper than the e6400, at least where I've been looking. Thanks for the chart.

However, I'm wondering if that little extra cache might help my horrible decompression rate. I've used 7-Zip and powerarchiver, both seem to decompress on my machine between 3500 - 4300 kps. Doesn't seem to matter what is being decompressed either. I know that this is getting off the topic of what I started but the reason I'm looking toward another processor is for this reason.

CPU: Intel e6400 CPU (stock speed)
MB: Asus P5NSLI Nvidia 570 Chipset
RAM: OCZ Dual Channel XTC 2048MB PC5400 DDR2 667MHz Gamer Memory
VID: Asus Radeon X1950 Pro 256MB
HD: 3x Seagate 320GB SATA2 in RAID 5

I am using the latest chipset drivers as well.

If you already have an e6400. It really isn't worth it one bit. Honestly I would hang on to your e6400 and overclock it and wait for the Quads to come down. That is the only way you are really going to see a large improvement.

On that chart, where is the 5400, 5600 and 6000? Not that I am a fan boy, i just want to see where they stack up at.
