Rumor has it that Nvidia will launch the RTX 5080 with 30 Gbps GDDR7 memory, while the rest of the Blackwell series will stick with slower 28 Gbps modules baseline life as found spring breeze Note that this also includes the flagship RTX 5090.
Nvidia’s RTX 50 series is expected to be the first GPU series to feature GDDR7 memory. GDDR7 offers several advantages over its predecessor, such as higher speeds and greater density. coming soon GDDR7 products Samsung promises speeds of up to 42.5 Gbps for 24Gb (3GB per module) capacity. Mainstream and budget GPUs have narrow bus widths, limiting VRAM capacity to a paltry 8GB or 12GB (128 bits/192 bits) when using 16Gb modules. While newer 24Gb modules could theoretically boost those figures to 12GB and 18GB respectively, they’re not expected to be available until 2025 or later, likely in super refresh form.
With this background in mind, Benchlife’s report suggests that Nvidia will use slower 28 Gbps GDDR7 modules in all Blackwell series GPUs except the RTX 5080. Like its predecessor, the RTX 5080 is rumored to have the fastest memory in the entire series, this time at 30 Gbps, which can deliver 960 GB/s of bandwidth if we assume a 256-bit memory interface. previous leaks It is suggested that the RTX 5080 will come with 16GB VRAM, and this configuration is only available for 16Gb modules and 256-bit interfaces, so our calculations are consistent.
Beyond that, AMD’s RDNA 4 is said to use fairly conservative memory settings and an 18 Gbps GDDR6 module. Likewise, the Intel Battlemage B580 comes in a 12GB configuration with 19 Gbps GDDR6 memory. Nvidia’s dominant position in the market gives them the ability to charge quite a lot for the latest technology, including GDDR7 VRAM.
Yesterday, there was news from Sotech Confirmed Nvidia is preparing to release the RTX 5090, RTX 5080 and RTX 5070 series in 2019 International Consumer Electronics Show next month. This suggests that the RTX 5060 series may be delayed until Q2’25, aligning its launch with the availability of 24Gb modules (at least from Samsung). This should allow for higher capacities, up to 12GB with the RTX 5060, but that’s just wishful thinking.
