GTX 1080Ti doing Terrible Preformance in Ray Tracing but similar specs?

[Alienware 15 R2]

Hi,

 

why is the GTX 1080Ti which has basically the same specs as an RTX 2080Ti Fail at Ray-Tracing?

 

I know that the Different GPU Architecture plays a Roll in Preformance over all.

 

GTX 1080Ti - Pascal

 

RTX 2080Ti - Turring

The GTX 1080ti doesn't have the RTX features like ray tracing cores which allow it to render ray tracing more efficiently. 

[Kilrah]

Just because the RTX cards have hardware cores dedicated to making those operations fast and efficiently.

 

Same as a high end CPU has a hard time decoding 4K video purely by software, but through the addition of a little bit of additional circuitry dedicated to that task a cheapo $50 tablet has no problem doing so.

The 1080Ti has far from the same specs as a 2080Ti.

Also, RTX cards have dedicated RT cores on them to specifically handle ray tracing, regarding your question.

[xAcid9]

That's like comparing 2x 2L engines with different horsepower. 

[Shimejii]

One has the Gimicky RT Cores that make it better, one doesnt.2080ti Has the Specifically designed cores as well as cuda cores and such for better ray tracing support (Its still garbage) Wheras the 1080ti wasnt.

Here’s some benchmark info from Userbenchmark.com

 

Hyped as the "Ultimate GEforce", the 1080 Ti is NVIDIA's latest flagship 4K VR ready GPU. It supersedes last years GTX 1080, offering a 30% increase in performance for a 40% premium (founders edition 1080 Tis will be priced at $699, pushing down the price of the 1080 to $499). It also supersedes the prohibitively expensive Titan X Pascal, pushing it off poll position in performance rankings. The 1080 Ti is based on the Pascal architecture and features a slightly modified version of the same flagship GP102 silicon found in the Titan X Pascal. It has 11GB of the high bandwidth GDDR5X video memory (versus 12GB in the Titan X Pascal) and an impressive 11GB frame buffer. Like the Titan X Pascal, it features 12bn transistors and 3584 CUDA cores which can run at a boost clock speed of 1.582 GHz – 3% faster than the Titan X Pascal's 1.531 GHz. This increased speed is partially attributable to the 1080 Ti’s new dualFET power system which allows the chip to run at higher power and more efficiently than ever before. The release of the 1080 Ti comes ahead of the competition from AMD's Vega - rumored for release in Q2 2017. Vega is AMD's next generation graphics card (following on from Polaris 10) featuring their new HBM2 die which is alleged to have eight times the capacity of GDDR5 with half of the footprint. NVDIA's own next generation graphics cards (Volta) are in the pipeline for 2018.

 

RTX 2080Ti

 

“Build it, and they will come” must be NVIDIA’s thinking behind their latest consumer-focused GPU: the RTX 2080 Ti, which has been released alongside the RTX 2080. Following on from the Pascal architecture of the 1080 series, the 2080 series is based on a new Turing GPU architecture which features Tensor cores for AI (thereby potentially reducing GPU usage during machine learning workloads) and RT cores for ray tracing (rendering more realistic images). Unfortunately, there aren’t (m)any games that make use of these capabilities so the $1200 price tag on the RTX 2080 Ti Founders Edition is difficult to justify. The 2080 Ti also features Turing NVENC which is far more efficient than CPU encoding and alleviates the need for casual streamers to use a dedicated stream PC. On paper the 2080 Ti has 4352 CUDA cores, a base/boost clock of 1350/1545 MHz, 11GB of GDRR6 memory and a memory bandwidth of 616GB/s. The upshot is that it has around a 30% faster effective speed than the 1080 Ti, which at 18 months old continues to offer comparable value for money and currently dominates the high-end gaming market. Professional users such as game developers or 4K gamers may find value in the 2080 Ti but for typical users (@1080p), prices need to drop substantially before the 2080 Ti has much chance of widespread adoption.

I'm not sure what point your making here with this info.

[Kilrah]

And it's not "benchmark info", it's marketing blurb.

[Alienware 15 R2]

Sorry for the marketing blurb up there.

that was just for me to verify the RTX 2080ti has 4,293 CUDA CORES and the GTX 1080Ti has  3,584.

thank you for Replying everyone.

 

but seriously would they’re be any way to get Stable raytracing on a 10 series card?

10 series are not RTX , so i don't think so...

[Alienware 15 R2]

Alright then thanks everybody for answering my question.

 

have a goodnight.
