Synthetics

As always we’ll also take a quick look at synthetic performance to see if NVIDIA’s core configuration has had any impact on basic performance metrics. Paper specifications tell us that texture fillrate should take a decent hit with pixel fillrate takes an even larger hit; and meanwhile tessellation should hold up fairly well. We’ll start with 3DMark Vantage’s Pixel Fill test.

As expected, the GTX 650 Ti drops off a cliff compared to the GTX 660. Despite this, it does rather well compared to the GTX 650 despite the similar ROP throughput and memory bandwidth of the two cards. It can even edge out the GTX 560 in the process.

Meanwhile 3DMark Vantage’s Texture Fill test backs up our earlier texture performance expectations. The drop compared to the GTX 660 is still large, but not by nearly as much as the pixel fillrate. Having twice as many SMXes as the GTX 650 also means that it comes close to doubling the GK107 card’s performance here.

Our third theoretical test is the set of settings we use with Microsoft’s Detail Tessellation sample program out of the DX11 SDK

So much for tessellation performance holding up. This is admittedly a high pixel throughput test (we’re measuring at 1000fps+), but it’s also a very simple test that doesn’t have a great deal of overdraw. Despite the fact that the GTX 650 Ti holds on to most of GK106’s Polymorph Engines, performance drops by 40% relative to the GTX 660, which is far more in-line with the loss of ROP throughput and memory bandwidth.

Our final theoretical test is Unigine Heaven 2.5, a benchmark that straddles the line between a synthetic benchmark and a real-world benchmark as the engine is licensed but no notable DX11 games have been produced using it yet.

Despite everything else we’ve seen, Unigine results are almost exactly in the middle of the expected performance loss between shading/texturing and ROP/memory on the GTX 650 Ti. This makes it just good enough to tie the GTX 560, or surpass the GTX 550 Ti by nearly 50%.

    Oh there's the amd fanboy bloviating spew I predicted above you responded to ! LOL I cannot frikkin believe it, I got it exactly correct without looking ! Here I will FTFamd fanboy

    " Don't forget, the 650Ti comes with a game and so does the 560Ti. Coming with a game is necessary just to compete right now. The 460 also has some highly factory overclocked models that can smash out the 7770 while still being cheaper. The 7850 would do better at $10 or $20 lower and a MIR is a great way to accomplish that since a lot of people forget to do them anyway, but buy the card because of the after MIR price. ( I love ripoff MIR because I am an idiot shining on for corpo pig profits I hate so much).

    2 of the 17 2GB 7850s on newegg comes with a game. I didn't bother checking the 1GB, b/c who cares about the 1GB? To say they comes with a game is a bit disingenuous.

    It's okay all the amd fanboys can get the lowest low down 1GB now at the cited lowdown more expensive price, that doesn't matter when they are making their arguments for amd fanboyism.

    Two seconds later they will be screaming the 7850 is future proof with 2g ram so F orget the 650Ti, it is also the best deal againbecause amd roxxors.

    So 1gb price, and magically in the deranged gourd of the amd fanboy 2G card is futureproof.
    That is the amd fanboy brain after it exited the blender 20 years ago.

    The 7850 is a better choice for one freaking big reason you Cerise wouldn't be able to see because you're blinded with green glasses. When you buy a 7850 you always have the choice to go crossfire in the future which is something that happens often in the enthusiast world.

    Usually GTX is branded for the enthusiast market and reffered as the better cards from Nvidia but hey, where is my SLI connector? Oh... there's none... they had to cut it for cost purposes, that's what Nvidia claims..... First time in history a GTX card comes without one... you're so stubborn you can't even see any downside when they're OBVIOUS..... HELL even half of the radeon 7770 comes with Crossfire support and some of them costs 120$...

    I see what you did there...

    I caught that too. Thought it was cute but kinda silly.

    Wonder how much of the target audience got it?

    I'd wager most of the AT readers passed middle school chemistry. :P
  • Paulman - Wednesday, October 10, 2012 - link

    Exodite is right. Also, nerds love memorizing trivia (and the periodic table definitely counts).
  • CeriseCogburn - Friday, October 12, 2012 - link

    I'll wager if that's minimally true we've got a dumber group than the general populace.
    Since the idiots group think yours was a great line, the above may in fact be the case.

    As indicated in the review, the 650Ti fills the huge gap in performance between the 7850/GTX 660 and 7770/GTX 650, its price just needs to be adjusted in light of AMD's pre-emptive cuts on the 7850. Once we start seeing ~$20 rebates similar to those we see for the 7850, the 650Ti should be a more appealing option in the sub-$150 range.

    I also think Nvidia missed an opportunity here by turning off Boost for sub-660 parts. It's just inconsistent with the rest of the Kepler line and while it allows partners to benefit on OC parts, they are clearly charging an additional premium instead of offering it at MSRP like past parts such as EVGA FPB.

    Most interesting to me seeing how these bandwidth neutered parts perform is how shading/backend performance has caught up and is generally no longer the biggest bottleneck; bandwidth tends to hold these cards back more often than not compared to their bigger siblings even at modest resolutions like 1080p.
