NVIDIA GeForce RTX 5090 Specs and Release Date

The GeForce RTX 5090 is expected to be 60 to 70% faster than the RTX 4090. Ray tracing performance and DLSS 4 are going to be the priority

NVIDIA is prepping the GeForce RTX 5090 for a late 2024 release. The Blackwell gaming flagship is expected to leverage the GB202 die, which features a 12×8 cluster configuration. This means the GPU will consist of 12 GPCs (Graphics Processing Clusters), each packing 8 TPCs (Texture Processing Clusters). A TPC comprises two SMs (Streaming Multiprocessors), also known as Compute Units (CUs). An SM consists of 128 FP32 cores (and 64 INT32 cores)

The NVIDIA SM (Compute Unit)

AD102 (Ada Lovelace)

Each NVIDIA SM has four partitions consisting of 32 FP32 cores, an L0 cache, a register file, a dispatch unit, and a warp scheduler. These are the fundamental scheduling blocks of GeForce GPUs. The Ada/Ampere SM partition can shuffle between (up to) 12 SMs at once.

NVIDIA GeForce RTX 5090 Release Date

Back to the GeForce RTX 5090, Moore’s Law is Dead claims that the Blackwell flagship will be the sole GeForce RTX 50 series launch of 2024. Furthermore, the YouTuber alleges it’ll be a paper launch with limited stocks till early 2025. The GeForce RTX 5080 is expected to launch in 2025, offering slightly more performance than the RTX 4090.

The GeForce RTX 5090 is expected to be 60 to 70% faster than the RTX 4090. Like Ampere and Ada, much of the focus will lie on ray tracing performance. Rasterization will be secondary, which is fine because the RTX 4090 crushes every rasterization load. You can also expect a new version of NVIDIA’s Deep Learning Super Sampling technology DLSS 4 with Blackwell.

NVIDIA RTX 5090 Specs: Core Count

NVIDIA will use a slightly cut-down GB202 graphics core for the RTX 5090. The chipmaker did the same with the RTX 4090 (AD102) and the RTX 3090 (GA102). With the current flagship, the design team went a little overboard with the scalpel, cutting out nearly 2000 shaders (FP32). The RTX 5090 should be much closer to the fully enabled Blackwell die.

The fully enabled GB202 die features 24,576 shaders spread across 192 SMs and 96 TPCs. Factoring in the SMs disabled for yields and segmentation, we can expect a core count of 24,046 or 188 SMs on the RTX 5090. If NVIDIA gets greedy, then like the RTX 4090, the RTX 5090 may come with a whole GPC disabled, reducing the shader count to 22,528 and 176 SMs.

NVIDIA RTX 5090 Specs: Memory and Cache

On the memory side, we’re looking at 32Gbps GDDR7 memory paired with a 384-bit bus. The L2 cache will be consolidated to 96MB as well. Plans of using a 512-bit bus seem to have been shelved. The GeForce RTX 5090, with 32Gbps GDDR7 memory and a 384-bit bus, would produce an external memory bandwidth of 1,536 GB/s, up from 1,008 GB/s on the RTX 4090.

The RTX 3080 Ti vs the RTX 4090

A 50% increase in memory throughput backed by a ~60% gain in shader density would easily net generational uplifts of up to 2x or more. It’s still too early to finalize a number, but it’d be fair to say that the RTX 5090 should deliver the same (level of) generational upgrade as its predecessor.

Regarding the ROPs/RB: if the RTX 5090 is derived from the GH202, it will contain 2x as many ROPs as each GPC would have an additional TPC and ROP cluster.

NVIDIA RTX 5090 Pricing

Then there’s the pricing. The GB202 and its siblings will be fabbed on TSMC’s cutting-edge 3nm node. These are some of the most expensive wafers on the planet. And there’s no competition from AMD. The Radeon RX 8900 XTX has already been canceled, and the fastest RDNA 4 GPU will offer RX 7900 XTX level performance. I expect a price tag of $2,000 for the RTX 5090, but it could go as high as $2,499.
