SYSMark 2007 Performance
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
SYSMark really taxes two cores most of the time, giving the edge to Lynnfield and its aggressive turbo modes. Lightly threaded or mixed workloads won't do so well on the Phenom II X6.
Adobe Photoshop CS4 Performance
To measure performance under Photoshop CS4 we turn to the Retouch Artists’ Speed Test. The test does basic photo editing; there are a couple of color space conversions, many layer creations, color curve adjustment, image and canvas size adjustment, unsharp mask, and finally a gaussian blur performed on the entire image.
The whole process is timed and thanks to the use of Intel's X25-M SSD as our test bed hard drive, performance is far more predictable than back when we used to test on mechanical disks.
Time is reported in seconds and the lower numbers mean better performance. The test is multithreaded and can hit all four cores in a quad-core machine.
Performance here is good, but even Photoshop doesn't make consistent enough use of all six cores to really give the Phenom II X6 the edge it needs here. It's faster than the Phenom II X4, but not faster than the Core i5 750.

While in general the upper end i5/i7 CPUs are a bit faster, there are other costs involved.Basic AMD boards are $80, upper end Cross-fire boards are $100~150, while typical P55 boards are $100~200, and X58s are $200~300.
So, with cost of the intels is about $150~400 in price to get a few seconds performance improvements.
Also, if someone buys a lower-end i3 CPU, they can't upgrade to a top end i7 CPUs because of different CPU sockets. While those who bought an AMD class board a year ago will most likely have the option to upgrade.

Who would want to run a six-core CPU on a two-year old board though?You wouldn't have things like USB 3.0, SATA 6 gbps, probably not even PCI-express 2.0 either.
I don't think it's a good idea to upgrade a CPU in the same board in general.
Usually the old board will severely hamper performance, so you're not getting your money's worth for the new CPU. And you'll miss out on the new features.
In all the years that I've been building PCs for myself and for friends/family, I have never found a CPU-upgrade very compelling, and I wouldn't recommend it to anyone.
I wouldn't be surprised if it's better to get a 1055T instead of a 1090T, and spend the extra money on a new board, rather than running the 1090T on the old board. There's a very interesting article in there for Anand I suppose.

Tested on Crosshair IV, th 1090T did far better than any i7... proves how much MSI and Gigabyte suck at this thing.hooga - Tuesday, April 27, 2010 - link
Can you please make a note of wheather or not all power saving functions like C"n" Q and C1 for PhenomII is activated?Anand Lal Shimpi - Tuesday, April 27, 2010 - link
All power saving features were enabled on all chips - C1E and CnQ were enabled on the X6. You need to enable these features otherwise Turbo Core doesn't work.Take care,
Anand

With 6 cores, memory bandwidth might be more important. The gain from DDR3 for Phenom II was minimal. Or is L3 cache bandwidth the bottleneck?hooga - Tuesday, April 27, 2010 - link
I meant C1E obviously, and what about overcloking? Just a half heartet attempt? makes me wonder if there is some fanb** no, im not going to say that word, iv always seen you guys as very professional and cant quite believe that, im hopeing that you post the 4,2GHz results very soon. :)silverblue - Tuesday, April 27, 2010 - link
Bit-tech couldn't exceed 3.89GHz with their sample. Guru3d managed 4.1GHz using an OCZ Vendetta air cooler.These things are usually quite variable.

That's certainly helpful.Considering the intended uses for this type of processor - i.e. heavily threaded applications - it offers more performance for the price as compared to anything Intel is throwing out.
Yes, Intel's products are faster per clock, but they just can't match AMD for performance at a given price point. Guru3D touched upon the point that you could build a 1055T machine for $600; that's $400 less than the 980 on its own. How much would it cost to build a 980 setup, or even a 930 solution in comparison?

Depends on where you buy stuff... Microcenter runs great deals on the i7/930 (around $200), for example.
