NVIDIA GeForce RTX 6080: Rumors About Specifications and Release Date

The NVIDIA GeForce RTX 6080 has not yet been officially announced. Currently, the latest high-end model below the RTX 5090 is the RTX 5080, based on the Blackwell architecture with GDDR7 memory, so all information regarding the RTX 6080 should be taken as early rumors rather than final specifications.

According to leaks, the RTX 6080 may feature a GR203 GPU, 20 GB of GDDR7, and a 320-bit memory interface. This would represent a significant leap forward compared to the RTX 5080, which typically offers 16 GB of GDDR7 and a 256-bit bus. The main gain in such a scenario would not only be in VRAM capacity but also in memory bandwidth.

The architecture is rumored to be related to Rubin or a gaming derivative of Rubin. However, the exact number of CUDA cores, clock speeds, TDP, and SM block configuration remain unknown. Some sources cautiously mention an increase of about 30-35% in regular graphics performance and a significantly greater jump in ray tracing/path tracing, but this pertains to rumors regarding the RTX 60 Series overall, not confirmed tests for the RTX 6080.

The release date is also unclear. The RTX 60 Series was previously expected in 2027, but recent reports increasingly suggest a possible shift to 2028 due to memory shortages and prioritizing AI accelerators for data centers.

Conclusion

The RTX 6080 currently appears to be a future graphics card for those who need high performance in 4K, heavy ray tracing, and greater video memory capacity than the RTX 5080. The most interesting rumor is the transition to 20 GB of GDDR7 and a 320-bit bus, as memory could become one of the main differentiators of the new card.

But for now, this is not a product with confirmed specifications. Until the official announcement, the RTX 6080 should be regarded as an anticipated model of the future RTX 60 Series, rather than a graphics card with already known parameters.

Tensor Cores
?
Tensor Cores are specialized processing units designed specifically for deep learning, providing higher training and inference performance compared to FP32 training. They enable rapid computations in areas such as computer vision, natural language processing, speech recognition, text-to-speech conversion, and personalized recommendations. The two most notable applications of Tensor Cores are DLSS (Deep Learning Super Sampling) and AI Denoiser for noise reduction.

TMUs
?
Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth
?
Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Theoretical Performance

Pixel Rate
?
Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.
313.6 GPixel/s
Texture Rate
?
Texture fill rate refers to the number of texture map elements (texels) that a GPU can map to pixels in a single second.

FP16 (half)
?
An important metric for measuring GPU performance is floating-point computing capability. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy.

Miscellaneous

SM Count
?
Multiple Streaming Processors (SPs), along with other resources, form a Streaming Multiprocessor (SM), which is also referred to as a GPU's major core. These additional resources include components such as warp schedulers, registers, and shared memory. The SM can be considered the heart of the GPU, similar to a CPU core, with registers and shared memory being scarce resources within the SM.

The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
