NVIDIA GeForce RTX 5080 to Stand Out with 30 Gbps GDDR7 Memory, Other SKUs Remain on 28 Gbps
NVIDIA is preparing to unveil its "Blackwell" GeForce RTX 5080 graphics card, featuring cutting-edge GDDR7 memory technology. However, RTX 5080 is expected to be equipped with 16 GB of GDDR7 memory running at an impressive 30 Gbps. Combined with a 256-bit memory bus, this configuration will deliver approximately 960 GB/s bandwidth—a 34% improvement over its predecessor, the RTX 4080, which operates at 716.8 GB/s. While the RTX 5080 will stand as the sole card in the lineup featuring 30 Gbps memory modules, while other models in the RTX 50 series will incorporate slightly slower 28 Gbps variants. This strategic differentiation is possibly due to the massive CUDA cores gap between the rumored RTX 5080 and RTX 5090.
The flagship RTX 5090 is set to push boundaries even further, implementing a wider 512-bit memory bus that could potentially achieve bandwidth exceeding 1.7 TB/s. NVIDIA appears to be reserving larger memory configurations of 16 GB+ exclusively for this top-tier model, at least until higher-capacity GDDR7 modules become available in the market. Despite these impressive specifications, the RTX 5080's bandwidth still falls approximately 5% short of the current RTX 4090, which benefits from a physically wider bus configuration. This performance gap between the 5080 and the anticipated 5090 suggests NVIDIA is maintaining a clear hierarchy within its product stack, and we have to wait for the final launch to conclude what, how, and why of the Blackwell gaming GPUs.

It's like a joke with deaf people.
In my opinion, the best looking card, so far, is the RTX5070Ti, depending on the price, it will probably be the best buy from the lot if you look at the specifications across all the cards.
Avoid until then. It's only purpose for now is to serve as a cynical upsell tactic for the 5090.
The fastest of current gen of VRAMs actually used for a GPU should be the 23Gbps on 4080S. A good 30% more bandwidth from memory change should be a good result. GDDR7 compared to GDDR6X also should have both simpler signalling as well as lower power consumption on top of that.
It happened once with the Ada series but now it becomes ridiculous.
i assume GDDR7 will be even worse. So anything that can reduce bandwidth needs is a good thing.
GPUs are still often enough bandwidth starved. So anything that relieves pressure on that bandwidth is good but in the end it is still important to have.
The RTX 4090 has 21 Gbps GDDR6X memory and the 7900 XTX has 20 Gbps GDDR6. That bandwidth increase is pretty substantial aside from the bus increase. I think the RTX 4080 SUPER had 23 Gbps GDDR6X chips.
