The Nvidia GeForce RTX 3080 will be the second most powerful graphics card in the 3000 series after the RTX 3090. The benchmark will be offered in three versions of 10, 20 and 24 GB of VRAM. The first has just been spotted on the Userbenchmark platform with several interesting details on its technical sheet.
The GeForce RTX 3080 is the subject of a major new leak as the launch of Ampere graphics cards approaches. A benchmark has just been spotted by the famous leaker Rogame on Twitter. The tested reference has 10 GB of video memory, which corresponds to the basic version of the graphics card. The RTX 3080 will indeed be available in 3 variants as we learned last week: a 10 GB version, a 20 GB intermediate model and an RTX 3080 Ti with 24 GB of VRAM.
RTX 3080: 2.1 GHz GPU frequency and 19 Gpbs memory speed
The version of the GPU that interests us here operates at a frequency of 2.1 GHz itself. The 10 GB of GDDR6X VRAM are operated through a 320-bit memory interface. The memory clock frequency is 4750 MHz. We therefore arrive at a speed of 19 Gbps and a bandwidth of 760 Gb / s. For comparison, the GeForce RTX 2080 Ti runs at a maximum clock speed of 1545 MHz and is equipped with an 11 GB GDDR6 VRAM for a memory speed of 14 Gbps. Its bandwidth is 616 GB / s.
Clearly, the base GeForce RTX 3080 outperforms the RTX 2080 Ti on paper. And we’re not even talking about the RTX 3090; the most powerful of the Ampere graphics cards which has regularly come to the fore for several weeks. Some leaks note that the actual clock speed of the RTX 3080 will probably be limited to around 1.7 GHz to stay in the same wake as the RTX 2000. A big jump is indeed very unlikely between the two generations on this. ground. But while some versions of GeForce RTX 3000 cards offered slower clock speeds, the efficiency and performance gains that Nvidia has achieved with the Ampere architecture should allow them to outperform Turing graphics cards, all else being equal. It is to be mentioned that the improved performance, especially in games that support ray tracing, should make the next generation GeForce graphics cards more appealing to gamers.
