GDDR6 is the current standard in VRAM used in Nvidia RTX GPUs. GDDR6 is significantly faster compared to GDDR5 but, this boost in performance comes at a premium. According to the report, GDDR6 VRAM is 70% more expensive compared to GDDR5.
The report comes from 3DCenter which notes that 14 Gbps GDDR6 VRAM from Micron Technology is 70% more expensive compared to 8 Gbps GDDR5 memory and from the same manufacturer.
While the 13 Gbps and 12 Gbps versions of GDDR6 are cheaper but, Nvidia uses the 14 Gbps for its RTX GPUs. Not only that, the rumored RTX 20260 will also reportedly use the 14 Gbps GDDR6 VRAM.
However, with such a price difference, expect Nvidia to roll out a potential GDDR5 version of the RTX 2060. As noted by Techpowerup, using GDDR5 saves GPU manufacturers around $22 per GPU.
Another reason for GDDR5 to be cheaper compared to GDDR6 could be the abundance of GDDR5 chips being in stock and Micron is looking to clear its GDDR5 stock.
Speaking of GPUs, Nvidia introduces its RTX 2080 and RTX 2070 GPUs that bring real-time ray tracing. These RTX GPUs feature RT Cores, which are responsible for handing ray tracing.
However, it seems that you don’t really need RT Cores to support real-time Ray Tracing. PC enthusiasts managed to run Battlefield 5 with real-time Ray Tracing enabled on Nvidia Titan V.
Interestingly, Titan V not only managed to run Battlefield 5 with ray tracing but, did so with an average of 80 FPS. However, this was done at a software level using DirectX 12.
But, this doesn’t mean you don’t need RT Cores as doing this at a software level requires a $2999 Titan with a sheer amount of graphical computing. What is interesting, Titan V’s performance is comparable to Titan RTX.
Speaking of Nvidia, the company is yet to reveal its mid-range RTX 2060 GPU. While we are waiting, leaks and rumors have almost confirmed Nvidia RTX 2060 reveal at CES 2019.
According to leaked marketing material, Nvidia is prepared to reveal its mid-range RTX 2060 at CES 2019 later this month. However, what is confusing is that RTX brand being attached to 2060.
Nvidia confirmed RTX 2070 to be the minimum requirement for ray tracing. Meaning, 2060 won’t support real-time ray tracing which makes the RTX branding confusing.
Does this mean Nvidia is backtracking on its statement and will include ray tracing support for RTX 2060? We will have to wait till CES 2019.
