Nvidia GeForce GTX 650 And 660 Review: Kepler At $110 And $230

Features
By published

We have two new graphics cards in the lab today: Nvidia's GeForce GTX 650 and 660, filling the gap between its GeForce GT 640 and GTX 660 Ti with Kepler derivatives. Are these GK107- and GK106-based boards able to challenge the Radeon HD 7750 and 7850?

OpenCL: GPGPU Benchmarks (Basemark CL)

Fluid Operations

The OEM GeForce GTX 660 ekes out a lead over the retail model. Both variants trail the GeForce GTX 660 Ti and 570 by a wide margin, though.

Wave Simulation

This time around, the tables turn and clock rate trumps compute resources. At the same time, Nvidia’s current generation doesn’t seem to improve performance compared to the Fermi-based cards.

The Radeon HD 7870 is the biggest surprise among AMD's cards, finishing ahead of the newly-boosted Radeon HD 7950. Overall, the field is grouped much tighter than in previous benchmarks.

Julia Rendering

Again, clock rate is king, and the GK106-based card beats out the OEM version of Nvidia's GeForce GTX 660, tying with the GTX 660 Ti.

Mandelbulb Rendering

While Julia rendering embarrassed Nvidia's hardware, the Mandelbulb test (a three-dimensional version of the Mandelbrot set) is far favorable to the Fermi- and Kepler-based cards. This is another test that rewards frequency over compute resources, and the GeForce GTX 660 comfortably holds its own against the GTX 580 and 570.

    Was waiting for GTX 650 to see if it can beat the old GTX 550 Ti but it seems other than power draw it's no match. Might as well keep my GPU until next NVidia lineup. GTX 660 on other hand is only €50 cheaper than GTX 660 Ti meaning its a no budget saver to buy non Ti version. Fail...

    Buy a 7770 or 7870 instead.
    Wait for sales on whichever one is needed and then grab one -
    AMD 7770 can be had for just over $100.
    AMD 7870 can be had for about $220.

    Goddamn Mike NY Gmail or whatever the hell your name is supposed to be, here, proper commenting etiquette:

    1. Read the article.
    2. Understand what the article is talking about.
    3. If you find an urge to comment about "______ sucks" or "_______ wins again", especially when the article says the opposite of what you want to post, chances are your comment will look dumb as hell when it's posted and earn you 20 downvotes. Therefore, don't post that goddamn poor excuse of a "comment".

    How "nice" of u tomshardware. By only compared 7750/7770 vs 650 in high detail but not comparing 7750/7770 on the Ultra detail, then when u pull out a 460 SE/9800GT for benchmark, u are taking away 650(why?).

    Is it because 650 performance is too poor to show off on benchmark? It doesnt take a genius to figure out the huge diff between 6870 vs 650. 7770= 6850 speed. So I guess even the 7750/460SE are putting shame on 650 on those high quality detail? too shy to show off 460SE/9800GT up against 650?

    I dare u put on a detailed benchmark with 650 up against 7770/7750/GTS450/550ti/460/9800GT/9800GTX on all condition. Not a selective benchmark.

  • Why are there giant gaps in both lineups? AMD has the 7770 at $130 and 7850 at $230 -- nvidia has the 650 and 660 at similar price points -- ideally for my budget would be something in the $150-170 price range, but I either have to compromise or shell out more. It seems like an obvious market gap.

    LaHawzelGod damn Mike NYThanks for the attempted compliment, but call me Mike. I'm glad you've been paying attention.

    It was more of a joke than anything else to simply write "AMD wins again!" and it was actually pretty funny! I try to balance things out so that no one company is viewed too favorably.

    For example, I recently bought an Nvidia GTX 460 1 GB 256 bit card for $70, new, with a 3 month warranty for a friend to upgrade his gaming computer. Unusual? Yes. Great deal? You better believe it! Of course, if an equivalent AMD card was available at a cheaper price, that's the one I would've bought.

    Now, relax and try to control yourself. Refrain from the use of profanity in future posts. Thanks.

    Nice article to be honest. I'm really glad you tested the Radeon cards with the new driver compared to other review sites.

    I've got nothing else to say on the GTX650 but to just point out that it's a weak card.

    On the other hand, the GTX660 is probably the only Kepler (besides the 670) that impresses me. I don't know about everyone else though. To point out one thing, most Radeon 7870s can be found at $240 or lower without MIR. The GTX660 is priced well for a release MSRP and makes the 660ti offers less value, kind of like the 670 vs 680. For 8xMSAA, the performance does cripple but I think at this price point, most people are going to stay with 4xAA or possibly lower.

    Exactly - Savvy TH readers will wait for sales on whichever one is needed and then grab one!
