Geforce GTX 670 vs Radeon HD 7970

Intro

The Geforce GTX 670 has core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs as well as 112 Texture Address Units and 32 ROPs.

Compare that to the Radeon HD 7970, which features a clock speed of 925 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

(No game benchmarks for this combination yet.)

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

The Corrupted Blood incident is a video game glitch and virtual plague that occurred on September 13, 2005 in the MMORPG World of Warcraft . The epidemic began with the introduction of the new dungeon Zul'Gurub and its end boss Hakkar who, when confronted and attacked, would cast on players a hit point draining and highly-contagious debuff spell called "Corrupted Blood." The spell, intended to last only seconds and function only within the new area of Zul'Gurub, soon spread across the virtual world when players discovered that the use of teleportation spells could take the affliction out of its intended confines.

If you like FPS games (Crysis, BF3 and Halo types) then Nvidia for sure and I would personally get the 670 over the 580 Look Here If you like Sports, racing simulators, MMORPG or Strategy games then ATI/AMD is the way to go and $20 more for the card would be worth it.

NVIDIA GeForce GTX 670 2GB GDDR5 is better than AMD Radeon HD 7970 3GB GDDR5, because it has a lower power consumption and it can be overclocked to the same performance as NVIDIA GeForce GTX 680 2GB GDDR5.

I personally went with the GTX670 for this "round", for a few reasons... However, I have had a lot of experience with the 7970 as well, and here are some notes.
First, the two systems:
My rig's important specs are 3x EVGA GTX670 FTW 2GB models in 3-Way SLI running at 1384Mhz GPU/7450Mhz-Effective VRAM, a GT650Ti 2GB for PhysX/Folding, a Rampage 4 Extreme, i7 3930K @ 4.8Ghz, 16GB DDR3-2133 9-11-10-28 (4x4GB OC'd @ DDR3-2400 9-12-11-28), Samsung 830 256GB SSD (OS/Boot), Plextor M5P-Extreme 256GB SSD (Games), 2x WD VR 1TB RAID0, 1x WD RE 4TB, (had to move my RAID setup to a dedicated Home Media Server), X-Fi Titanium HD, all custom water cooled (CPU/GPU's/MB/RAM).
My friend's rig consists of 2x MSI R7970 Lightning GHz-Edition 3GB in CF-X (1250Mhz Core/6600Mhz-Effective VRAM), a 650Ti 1GB for PhysX, Gigabyte GA-Z77X-UP7 Motherboard, i7 3770K @ 4.9Ghz, 16GB Samsung 30nm RAM DDR3-1600 11-11-11-30 1.35V (4x4GB OC'd @ DDR3-2600 11-13-11-31 1.585v), Samsung 840Pro 128GB (OS/Boot/Apps), 180GB Intel 330 SSD, LSI 9680-16i RAID Controller Card w 4GB Cache and BBU, 4x Seagate 7200.13 2TB HDD's RAID0, 6x Hitachi Ultrastar 500GB RAID0, 4x Seagate 3TB 7200rpm HDD RAID5+HS, and the CPU and GPU's are custom water-cooled (MB Block is on its way).

We have friendly benchmarking competitions all the time, but we also game a lot.
Occasionally, I will disable one of my 670FTW's so that we have "fair" 2vs2-card benchmarks (one reason that we both have dedicated PhysX cards, aside from BL2).

Despite his advantage in VRAM, we both end up with scores that are within 5% of one another, max, typically around 2%. This includes Heaven3.0, 3dMark11, etc. I do have a significant advantage in SuperPi/HyperPi/CineBench because of having 50% more CPU Cores/Threads, even if they are running 100Mhz slower and at a 5-10% IPC disadvantage.

When it comes to gaming, though, it's almost impossible to differentiate the two. Both of us can keep Far Cry 3 at >100fps at ALL times running everything on ULTRA at either 1080p or 1440p; Crysis and Crysis2 are >75fps with everything completely maxxed and with the DX11 Texture pack at the same resolutions, and even Metro2033 at 1440p with everything completely maxxed out will not drop below 50fps (Avg 78/88, Min 51/52, Max 131/178; mine scores a bit higher, but the minimum framerate is very similar... likely due to his VRAM advantage).

At the end of the day, we each paid EXACTLY the same amount of money for our cards, a whole $1.28 difference between the two GPU setups.
AND THEY BOTH ARE AWESOME!!!

(FWIW, I have used 3-way EVGA GTX680 4GB SLI, and it was all of 1.2-2.6% faster than my current setup, yet cost $500 more!)
