We're at a place in PC gaming where buying a top of the line video card is starting to look interesting again. A few things made that happen. First, 4K monitors finally became a reasonable purchase for desktop users, with the release of 60Hz IPS panels like the Dell 2715Q I've been using. 1080p 60Hz gaming doesn't require a $500 GPU, but the horsepower is welcome when gaming at 4K or 1440p at 144Hz. Second, we know that impending virtual reality gaming on the PC is going to require fast graphics--90Hz is the baseline for both Oculus and SteamVR, and we're expecting displays of at least 1080p from both. For high-end gamers, performance is a practical need once again; extra frames aren't just for show.
Nvidia's GeForce GTX 980 card seemed to address that need. It's both powerful and power-efficient, thanks to its second-generation Maxwell GM204 core, and its launch was well received by reviewers and gamers alike (aside from the GTX 970's recent memory revelations). And while I still think that the GTX 980 is a great buy for anyone building a new high-end PC, it's no longer the best option available. That title now belongs to Nvidia's new Titan X, which goes on sale this week. I've been testing one for the past week for 4K gaming.
The GeForce Titan X
I'm not going to dive into the deep technical attributes of the Titan X; what you should know that it's on paper a 50% bump up from the GTX 980. There are 50% more CUDA cores (3072 vx 2048), 50% more texture units, and 50% more transistors. Essentially, it's a fully loaded Maxwell GPU (GM200), and Nvidia even packed 12GB of GDDR5 memory in thing for future-proofing. That's more than enough for future ports of next-gen console games (surpassing the PS4's 8GB of GDDR5).
As with previous Titan class GPUs, the packing of so much CUDA cores into a single die offsets the need for a high core clock--Titan X starts at 1000MHz and boosts to 1075MHz, compared to the GTX 980's 1216MHz at load. That's necessary to keep the thermal load at a "reasonable" 250 watts, which is in line with past Titan cards and the power hungry Kepler-class GTX 780. That means that you don't get as much overclocking headroom with the Titan X as you would the GTX 980, which sits at a comfortable 165W TDP. And with the same cooling design as the GTX 980, the Titan X is just as quiet at idle as its sibling, and only very slightly louder at load. Maxwell's efficiencies don't go to waste here. The upshot is that Titan X relies on more cores instead of higher clock speed for performance. It's a scaled up version of the GTX 980's GPU--the largest Nvidia's made so far--to squeeze out frames needed for smooth 4K gaming. It also costs almost twice as much as a GTX 980 at $1000.
So let's take a look at some benchmarks and see what a thousand dollars of video card gets you today.
