Huge RTX 5090 performance gains teased by reliable leaker

Reliable leaker teases 70% performance gains for Nvidia’s RTX 5090 graphics card

Nvidia’s hard at work creating next-generation products, including an RTX 5090. This is the case for all of Nvidia’s major markets. While Nvidia has become more focused on AI in recent years, gamers can expect next-generation GPUs from the green team, and rumour has it that these GPUs will be “Blackwell” series products.

Thanks to a leaker called panzerlied, who has previously released accurate hardware details for Nvidia graphics cards, we now have some hardware details for Nvidia’s RTX 50 series of products. Nvidia’s RTX 50 series is due to land in early 2025. So please take these early details with a grain of salt.

The first detail from panzerlied’s report is that Nvidia’s Blackwell gaming flagship should feature 50% more memory bandwidth. This bandwidth likely comes from Nvidia’s use of GDDR7 memory. This points towards Nvidia’s Blackwell gaming flagship using a 386-bit memory bus and 31.5 Gbps GDDR7 memory. Samsung and Micron have already confirmed their plans to make GDDR7 memory, so we can expect GDDR7 to be used on next-gen GPUs.

Nvidia’snext-gen flagship allegedly features an 78% increase in cache size, presumably L2 cache size. This would give Nvidia’s RTX 5090 128MB of L2 cache, which is a huge upgrade. With Nvidia’s RTX 5090 featuring a core frequency boost of 15% over their RTX 4090, Nvidia’s next-gen flagship could clock at 3+ GHz clock speeds in many gaming workloads.

Nvidia’s RTX 5090 reportedly achieves 70% performance gains over its predecessor. These gains will come to  Nvidia’s next-gen GPU thanks to additional CUDA cores, and/or increased per core IPC. Assuming that Blackwell doesn’t come with huge IPC increases, expect Nvidia’s RTX 5090 to feature around 24,000 CUDA cores
