NVIDIA has been teasing its next-gen GeForce RTX 50 “Blackwell” series, with GB202, GB203, GB205, GB206, and GB207 GPU configurations out today. The next generation GeForce RTX 50 “Blackwell” GPUs are in the works by NVIDIA for gamers and details are being teased by leaker, Kopite7kimi. So to set the table and establish what the base specs for each new Blackwell Gaming GPU are going to be, we’ll assume that they are built on these core specs.

At the top, NVIDIA GB202, will be the flagship GPU die for GeForce RTX 50 “Blackwell” series. This beast will power ultra-enthusiast GeForce RTX 5090 and beyond. The GB202 GPU boasts 12 SMs, with 8 TPCs per SM, totaling 96 TPCs, and each TPC accommodates 2 SMs, amounting to 192 SMs. It also supports a 512-bit wide memory bus interface that is split up into flexible configurations including 448-bit, 384-bit, 320-bit, and others.
The NVIDIA GB203 GPU, which is targeted toward high-end enthusiast gamers, has 7 GPCs, 6 TPCs per GPC, and 42 TPCs in total, resulting in 84 SMs. The latter has a 256-bit bus interface, and will reportedly underpin the GeForce RTX 5080 graphics card.
NVIDIA GB205 is a mid-tier of high-end performance. The NVIDIA GB205 is the successor to the NVIDIA GA104 and is used to power the GeForce RTX 5070 and RTX 5070 Ti graphics card sisters. This consists of 5 GPCs, 5 TPCs per GPC for a total of 25 TPCs, as well as 50 SMs, with a 192-bit memory bus setup.
The NVIDIA GB206 GPU has 6 TPCs per GPC or a total of 18 TPCs (36 SMs) for 36 SMs on the NVIDIA GB206 GPU for mainstream gamers. This card has a 128-bit bus interface and as a result, it may turn out to be sufficiently pathetic for the next-generation GeForce RTX 5060 (Ti) family. Finally, the NVIDIA GB207 GPU for entry-level models like the GeForce RTX 5060 or RTX 5050, is constructed with 2 GPCs and 5 TPCs each for a total of 10 TPCs and 20 SMs. The chip works with a 128-bit memory interface, which may allow both GDDR7 and GDDR6 memory to be supported.
Finally coming to the launch timeline, NVIDIA is apparently looking at a number of cooling solutions with the flagship GeForce RTX 5090 SKU to feature a dual-slot/dual-fan design. The RTX 50 family is anticipated to debut later this year, with the RTX 5080 arriving first followed by the RTX 5090. However, there are indications that the lineup may be delayed until early 2025, as suggested by discussions with manufacturers during Computex. Additionally, the laptop GeForce RTX 50 lineup, featuring at least six SKUs with up to 16 GB GDDR7 memory, is expected to debut in early 2025 alongside next-gen Arrow Lake-HX and Fire Range-HX designs.
