NVIDIA GeForce GTX 1070 Ti

Here is my GPU profile for the GeForce GTX 1070 Ti, a graphics card released in late 2017 to fight off AMD's Radeon RX Vega 56, which solidly beat the original GTX 1070. The Ti variant features more active Streaming Multi-processors but retains the same GDDR5 memory sub system as the original 1070.

The card I owned was the ASUS "Turbo" blower. I really quite liked it actually.

Graphics Card description

GeForce GTX 1070 Ti launched in late 2017 to combat AMD's Radeon RX Vega 56, which handily beat the original GTX 1070. NVIDIA's response was to enable four more Streaming Multi-processors on the GP104 silicon, putting the GTX 1070 Ti really close to the GTX 1080 in core count with only one disabled SM from a full chip, but keeping the same regular GDDR5 (non X) memory sub system as the normal 1070. The result is a card that could take back the performance crown from RX Vega 56, but also cost 50 dollars more. In 2019 it is often seen that GTX 1070 Ti and RX Vega 56 are evenly matched and offer about the same performance on average, with the 1070 Ti consuming less power, but lacking advanced features such as doubled-speed FP16 shading, which the Vega 56's Vega 10 processor innately supports.


Graphics Card approximate 3D Performance

Sashleycat gaming performance rating (2019): Good for 1440p high settings 60 FPS

NVIDIA's GTX 1070 Ti was launched in late 2017 to beat AMD's RX Vega 56 graphics card, which was more performant than the original GTX 1070. On release the 1070 Ti managed to take back the performance crown in this segment from the Vega 56, often providing performance around the Vega 64 and only a bit behind the GTX 1080. In 2019, the Vega 56 somewhat closes this lead and the two cards are very evenly matched. Performance is comparable to an RTX 2060 of the 20 series and is well suited for maximum detail high refresh 1080p gaming. The card also can cope well with 2560x1440 resolution in many games.



Graphics Engine Clock

GPU Boost on Nvidia cards of this generation results in higher observed core clock speeds in actual games. The 1070 Ti will often run at upwards of 1800 MHz if power or thermal limits are not reached. The number here is the NVIDIA-spec boost rating. Please note all the peak performance figures are using this base spec number. Actual performance will be higher but it's impossible to exactly quantify what each card will boost to.


GPU Primitive Rate

Raw triangle output based on my understanding of the Raster Engines. PolyMorph engines attached to each TPC may have an effect on total triangles rastered.


Ayschronous Compute Capability

As far as I know Pascal GPUs are unable to execute graphics and compute tasks asychronously. However, I am listing it as "Limited" due to this architecture's ability to switch between both tasks very quickly and this allows Pascal to still do very well in frames requiring both types of workload. This is still effective for Pascal. To my knowledge Pascal would not have benefitted a lot, if at all, from true Asynchronous Compute Capability

Stream Processors per Graphics Core

If you count the very small number of Dedicated FP64 and FP16x2 Cores this would be higher but for simplicity's sake they are listed as special execution units not towards the Core's full ALU compliment (that are used in games).


This bit is for my personal opinion on this Graphics card / Graphics processor
