[The Tech Report] Radeon HD 7950 vs. GeForce GTX 660 Ti revisited

Quote:
Doesn't seem that long ago, back in August, when the GeForce GTX 660 Ti first hit the scene and squared off against the Radeon HD 7950. That match-up ushered in a new generation of competition among ridiculously powerful video cards at around 300 bucks. Nvidia had the advantage going in, since it was facing off against an already established competitor; it knew what the GTX 660 Ti had to do in order to win. AMD, however, has been unusually feisty lately, and it had other ideas. At the last minute, the Radeon team rolled out a new BIOS that added dynamic clock speeds to the 7950. The result was an incredibly slight win for the GTX 660 Ti on points, but in the end, we threw our hands up and said the differences mattered little.

We're vaguely astonished by how much things have changed since then.

Of course, we have a new crop of games for the holiday season, headlined by titles like Borderlands 2, Hitman: Absolution, Sleeping Dogs, and Assassin's Creed III. AMD's newfound aggressiveness means many of these games are part of its Gaming Evolved program, so they should run very well on Radeon graphics cards—and maybe, you know, not so well on those pesky GeForces.

In fact, accentuating its stronger ties to game developers, AMD has taken to bundling a trio of these games with its Radeon HD 7950 cards. Cramming that sort of gaming goodness into the box with a graphics card certainly changes the value equation.

As if that weren't enough, AMD has also released Catalyst 12.11 beta drivers that promise a roughly 15% across-the-board performance increase for its 7000-series Radeons. New drivers often bring performance gains for individual games, but general improvements of that magnitude are uncommon. AMD tells us it has employed new insights in tuning its relatively young GCN architecture.

What's more, Windows 8 is out, and we've transitioned our test rigs to the new operating system.

Add up all of these changes, and you have a recipe for realignment in ongoing battle for GPU supremacy. Are we still at rough parity, or have AMD's bold moves allowed it to push into the lead? We've deployed our infamous "inside the second" testing methods with a host of the latest games in order to find out.
Quote:
In the end, we're left to confront the fact that the biggest change from our prior graphics reviews was the influx of new games and new test scenarios that stress the GPUs differently than before. (The transition to Windows 8 could play some role here, but we doubt it.) For whatever reason, AMD's combination of GPU hardware and driver software doesn't perform as well as Nvidia's does in this latest round of games, at least as we tested them. That's particularly true when you focus on gameplay smoothness, as our latency-focused metrics tend to do.


EDIT:

First news post, should this have gone in Graphics General?

Sorry

I just read that review and it picked every single game that is going for the GTX600 series strengths and none of it's weaknesses. Every, single, game they decided to test has always and is well known, to run crap on the 7000 series GPU.

That review was biased and unfair to be honest.

From the Same review:

Drivers: GeForce 310.54 beta vs Catalyst 12.11 beta 8

Core Clock 1033 mhz vs 850 ( reference 660Ti= 915mhz, reference 7950 = 800mhz)

Boost Clock 1111 vs 950

Memory Clock 1652 vs 1250

I am a bit surprised that a 660Ti with 192 bit memory bus and 2G Vram is matching or exceeding 7950 performance on 2560X1440 resolutions.

They didn't test over clock performance, so who cares?

Sorry. I just noticed that Hitman and Sleeping Dogs are part of the "Never Settle Bundle" so i just assumed they would be good comparisons. Oh well..

Don't be sorry smile.gif I wasn't having a go at you, I'm pleased you posted it, I enjoyed reading it. However, through no fault of your own, it's a terrible comparison for the two cards because every game there is known to be terrible on the 7000 series GPU.

It was a good read, but I personally found it to be biased to the GTX, Thanks for posting it mate, really biggrin.gif

Um, no, sleeping dogs is usually better on the 7000 series than the 600 series, same goes for MOH warfighter after the 12.11 betas, and Skyrim also

Not sure what you're even talking about

Yeah, kind of a biased review. That said they are still fairly close in performance at stock.

Also, i'm pretty sure the nvidia drivers aren't in beta, while amd are constantly updating with new betas to work out issues with the new games. You can't sit there and say the amd card has shotty performance when it's a brand new, nvidia favored game.

Hmm I liked reading about the latencies of each card in processing frames. How this affects my next GPU not entirely sure yet, but if this is consistent between AMD and Nvidia it may suggest why I picked Nvidia cards more often than AMD cards in real practice.

Bullcrap, you have to consider much more than just the performance.

What is the price? Do you want to overclock?

If the 7950 is much cheaper (currently cheapest 7950 is @ 280$) and can be overclocked to 1.1 - 1.2 GHz quite easily, I would go for the 7950.
The cheapest to date 660ti is 290$.

In this situation, if you don't want to overclock, I would get the 660ti. If you do want then 7950 hands down.

Prices took from a canadian bot (shopbot.ca)
