Nvidia unveils GTX 1080 Ti: ‘faster than Titan X Pascal’
Nvidia has finally confirmed its most worst-kept of secrets. The GeForce GTX 1080 Ti is coming next week and the firm claims that the $699 card is actually faster than the $1200 Titan X Pascal. If you’re looking for a more affordable PC GPU capable of delivering graphically rich 4K gameplay at 60fps, this is the product for you.
In producing a Ti spin-off of a Titan product, Nvidia has historically chosen a number of approaches — culling CUDA cores and/or dropping the amount of VRAM included on the board. These downgrades usually have a fairly minimal impact on performance but regardless, GTX 1080 Ti actually has the most minimal cuts we’ve seen. Essentially, the 12GB of GDDR5X is reduced to 11GB — a very odd compromise, it has to be said — which means that the memory interface is bumped down from 384-bit to 352-bit, ROP count drops from 96 to 88, while 256K of the Titan X Pascal’s L2 cache is also omitted.
It’s highly unlike that we’re going to notice the missing gig of RAM and Nvidia has mitigated the effects of the drop in memory bandwidth by using higher speed GDDR5X — 11gbps vs the 10gbps modules found on the Titan X Pascal. The end result is that GTX 1080 Ti actually has marginally more bandwidth than Titan X Pascal. From our perspective, the question is how far it can be overclocked further — we already run our Titan X memory at 11gbps with a rock-solid overclock. With 4K gaming, memory bandwidth really is at a premium and needs to be pushed as far as it can go.
The really good news is that Nvidia hasn’t felt the need to compromise the CUDA core count of the GTX 1080 Ti at all. It still features the same 3584 shaders as the Titan X (there’s still more GPU power left untapped on the GP102 processor — the full chip actually features 3840 cores in total). Nvidia has also tweaked boost clocks on the GTX 1080 Ti to run the chip slightly faster than its Titanic stablemate. Taking all of this into account, a stock GTX 1080 Ti should indeed match or marginally outperform Nvidia’s current top-tier $1200 GPU, at less than 60 per cent of the price.

In terms of comparisons to the previous GeForce GPU halo product — GTX 1080 — Nvidia says we’re looking at a 35 per cent increase in performance, which it says is that largest bump to frame-rates ever seen from a Ti product. This is something we’re looking forward to testing. In the meantime, the arrival of the $699 Ti sees the GTX 1080 retail price drop by $100. On top of that, card manufacturers are going to start shipping 1080s and 1070s with faster memory. The 11gbps G5X modules found in the new Ti will also be available in select GTX 1080s, while GTX 1070 receives the option of 9gbps GDDR5. It should be stated that in our experience, existing versions of both GPUs can have their RAM overclocked by the user to match this throughput with zero effort. Again, from our perspective, the question is to what extent this new memory can be overclocked safely still further.
Returning to the GTX 1080 Ti, this is an exciting release for many reasons, but principally because the raw GPU power is there to provide native 4K gaming at 60fps with only minimal tweaks on the majority of titles. If you take a look at this benchmark run, you can see Titan X performance at 4K relative to the same content being tested at 1080p on a GTX 970 — which for many remains the quintessential card for 1080p60 PC gameplay. Let’s just say that the results are very, very close. Titan X Pascal was also our chosen hardware for running Forza Horizon 3 at a pretty much locked 4K 60fps. The experience is simply incredible, and based on the specs, GTX 1080 Ti should offer equivalent performance.
GTX 1080 Ti is set for a worldwide launch next week (UPDATE: New PR we’ve just received says that the card launches on March 10th, but there’s no UK pricing yet) and our sample should be arriving imminently. There’ll be Founders Editions with enhanced cooling compared to the GTX 1080 (and no price premium) and third party cooling solutions from the likes of MSI, Asus and others should allow for some interesting overclocking results.
In our testing, Titan X could be pushed further, but excessive heat was definitely a limiting factor. We’ll have a full review next week.
Nvidia GTX 1080 Ti vs Titan Xp: a comparison
So the
GTX 1080 Ti’s reign as fastest graphics card was short lived. For about a month it was the fastest consumer graphics card you could buy, but that honour has now been taken by the
new Titan Xp.
We knew it was coming, just like last year’s Titan X eclipsed the
GTX 980 Ti, but whether or not you consider it a ‘consumer’ graphics card is another matter.
In any case, the Titan Xp is here and we’re comparing it against the GTX 1080 Ti for specs and price.
Next year, or possibly later in 2017, it’s rumoured that the next generation of GeForce cards will be launched. Read

Nvidia GTX 1080 Ti vs Titan Xp: Price and availability
The GTX 1080 Ti Founder’s Edition, which is essentially Nvidia’s own card, costs
£699 from Amazon, or
$699 if you’re in the US.
That’s hardly cheap – you can buy an entire PC for less – but the $1200 Titan Xp certainly makes it look like good value.
The UK price is marginally less in pounds – £1,159 to be precise.
It’s only
available direct from Nvidia at the moment but will shortly be on sale through various system builders as well.

best graphics cards to buy if you’re looking for an upgrade.
Oddly, the new card looks identical to the old one, even down to the Titan X lettering – it doesn’t say Titan Xp.
The main reason for the similarity is because, underneath, these are basically the same card, just tweaked.
The Titan Xp is based on the same GP102 graphics processing unit as the 2016 Titan X (and the GTX 1080 Ti) but has 30 SMs (streaming multiprocessor units) enabled rather than 28 for the Titan X (and GTX 1080 Ti).
This means it has the ‘full’ complement of 3840 CUDA cores, and its RAM has also been boosted to give a bandwidth of almost 550GB/s compared to 480GB/s for the Titan X and 484GB/s for the GTX 1080 Ti.
There’s still the same 12GB quantity as the old card though, and 1GB more than the GTX 1080 Ti.
Power requirements remain the same, and Nvidia says you need a minimum of a 600W PSU to run the card, the same for all three cards.
Physically, the Xp has the same dimensions as the GTX 1080 Ti and Titan X at 267x111mm. You can buy an SLI bridge in 2, 3 or 4-slot widths for £35.99.
Performance remains to be seen, but it will take the crown from the GTX 1080 Ti, which had already taken it from the 2016 Titan X. Whether the increase is worth spending over £400 extra over a GTX 1080 Ti is debatable – most gamers will be just fine with a
GTX 1080 for under £500 without even stepping up to the £700 Ti model.
If you already have last year’s Titan X beating away in your PC, then you might be doubly annoyed that there are now two new, faster cards. But you can still rest easy in the knowledge you have one of the quickest cards around and there’s really no need to upgrade. Yet.

Mac compatibility
At last, Nvidia has promised Mac drivers for Pascal this month – April – which will not only work with the Titan Xp, but all 10-series GeForce cards, which means we will surely see an upgraded Mac Pro soon enough.
