AMD Radeon RX 7700 XT vs NVIDIA Rubin GPU Comparison

# Where Each One Wins

The AMD Radeon RX 7700 XT and NVIDIA Rubin GPU occupy completely different segments of the hardware landscape, and the recorded data reflects this stark divide. The RX 7700 XT is a consumer-focused graphics card with a substantial suite of benchmark results across DirectX 10, 11, 12, and 9, plus OpenCL and Vulkan tests. Its strongest showing comes in the Geekbench OpenCL test, where it scores 138,383, and in the 3DMark Steel Nomad DX12 test at 3,316. The PassMark G3D score of 22,547 and G2D score of 1,161 further establish its position as a mainstream gaming and workstation GPU.

The NVIDIA Rubin GPU, by contrast, has no recorded benchmark scores in the database. Its benchmark array is empty, with zero wins in any head-to-head comparison. This absence of test data means the Rubin GPU cannot be evaluated on the same performance metrics as the RX 7700 XT. Instead, its strengths are defined by architectural specifications rather than measured outcomes. The Rubin GPU is described as a server-class part from the "Server Rubin (Rxx)" generation, with an enormous 288 GB of HBM4 memory and a 16,384-bit memory bus delivering 22.1 TB/s of bandwidth.

The use-case split is therefore unambiguous: the RX 7700 XT wins every measured benchmark category simply because it has been tested, while the Rubin GPU has no benchmark data to contest those wins. The RX 7700 XT is positioned for consumer gaming and general-purpose compute with its DirectX 12 Ultimate support and Vulkan 1.4 compatibility. The Rubin GPU, lacking display outputs entirely and listing DirectX, OpenGL, and Vulkan as N/A, is built for server workloads where graphics API compatibility is irrelevant. The data indicates that any comparison between these two parts must focus on architectural intent rather than benchmark outcomes, as the Rubin GPU's performance profile remains entirely unmeasured.

# Architecture Differences

The architectural gap between these two GPUs is generational and foundational. The AMD Radeon RX 7700 XT uses the Navi 32 chip built on RDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It contains 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million transistors per square millimeter. The NVIDIA Rubin GPU uses the GR100 chip on the Rubin architecture, fabricated on a 3 nm process, also at TSMC. Its transistor count is 336,000 million, spread across a 1,456 mm² die, for a density of 230.8 million transistors per square millimeter.

The clock speeds reveal different design priorities. The RX 7700 XT runs at a base clock of 1435 MHz, a boost clock of 2544 MHz, and a game clock of 2171 MHz. The Rubin GPU has a much lower base clock of 700 MHz but a boost clock of 2267 MHz, close to the RX 7700 XT's boost. The Rubin GPU's memory clock is 2695 MHz with 10.8 Gbps effective, while the RX 7700 XT's memory clock is 2250 MHz with 18 Gbps effective. Despite the higher effective memory speed on the RX 7700 XT, the Rubin GPU's memory subsystem is vastly larger.

Shader resources diverge sharply. The RX 7700 XT has 3,456 shading units, 216 texture mapping units, and 96 ROPs, with 54 ray tracing cores and no dedicated tensor cores. The Rubin GPU has 28,672 shading units, 896 TMUs, and only 24 ROPs, with 896 tensor cores and no listed ray tracing cores. The pixel rate of the RX 7700 XT is 244.2 GPixel/s, far exceeding the Rubin GPU's 54.41 GPixel/s, while the texture rate is 549.5 GTexel/s versus 2,031.2 GTexel/s for the Rubin GPU. FP32 compute is 35.17 TFLOPS for the RX 7700 XT versus 130.0 TFLOPS for the Rubin GPU, and FP16 is 35.17 TFLOPS (1:1) for the AMD part versus 260.0 TFLOPS (2:1) for the NVIDIA part.

The memory configurations reinforce the server-versus-consumer split. The RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The Rubin GPU has 288 GB of HBM4 on a 16,384-bit bus with 22.1 TB/s bandwidth. Power consumption scales accordingly: 245 W TDP for the RX 7700 XT versus 2300 W for the Rubin GPU. The RX 7700 XT is a dual-slot card with 2x 8-pin power connectors and a 550 W suggested PSU, while the Rubin GPU is an SXM module with no listed power connectors and a 2700 W suggested PSU.

# Head-to-Head Benchmarks

The head-to-head benchmark array between these two GPUs is empty, containing no tests and recording zero wins for either side. The RX 7700 XT has its own benchmark scores, but the Rubin GPU has none. This absence of comparative data means the only quantifiable head-to-head analysis comes from the RX 7700 XT's nearest rivals in the database.

The RX 7700 XT's average benchmark score is 22,549, placing it at the 67th percentile among all GPUs. Its nearest rivals are all NVIDIA or older AMD parts. The NVIDIA GeForce RTX 5060 Mobile has an average score of 22,435, which is 0.5% behind the RX 7700 XT. The NVIDIA GeForce RTX 4060 Mobile scores 22,729, putting it 0.8% ahead of the RX 7700 XT. The NVIDIA GeForce RTX 2080 scores 22,895, which is 1.5% ahead. The AMD Radeon RX 5700 scores 22,170, sitting 1.7% behind the RX 7700 XT.

These deltas are small, all within 2%, indicating that the RX 7700 XT sits in a tightly competitive cluster. The RX 7700 XT's specific benchmark scores show strength in OpenCL compute at 138,383 and Vulkan at 46,443, while its PassMark DirectX scores are more modest: 119 for DirectX 10, 232 for DirectX 11, 79 for DirectX 12, and 294 for DirectX 9. The PassMark GPU Compute score is 12,912. These numbers suggest that the RX 7700 XT excels at compute-oriented workloads relative to its DirectX gaming performance.

The Rubin GPU's zero benchmark scores and empty nearest-rivals list mean it cannot be placed in the same competitive frame. The recorded data simply shows no measured performance for this part. Any attempt to compare the two directly would require extrapolation from specifications, which the database does not support for benchmark analysis.

# The Verdict

The data presents a clear division: the AMD Radeon RX 7700 XT is a measured, consumer-oriented GPU with a complete benchmark profile, while the NVIDIA Rubin GPU is an unmeasured server part defined entirely by specifications. For any workload requiring DirectX, Vulkan, or OpenGL support, the RX 7700 XT is the only viable option, as the Rubin GPU explicitly lists these APIs as N/A. The RX 7700 XT's 12 GB of GDDR6 memory and 432.0 GB/s bandwidth suit gaming and general compute, and its 67th percentile ranking among all GPUs places it above half the field.

The Rubin GPU, with 288 GB of HBM4 memory, 22.1 TB/s bandwidth, and 130.0 TFLOPS FP32 compute, is built for server-scale workloads where memory capacity and raw compute outweigh graphics features. Its 896 tensor cores and 260.0 TFLOPS FP16 performance (2:1) indicate a focus on AI and scientific computing, not rasterization. The absence of display outputs confirms this server-only role.

The recorded data does not support any benchmark-based comparison between these two, as the Rubin GPU has zero scores. The RX 7700 XT's nearest rivals are all NVIDIA GeForce parts or the AMD Radeon RX 5700, with deltas ranging from 1.7% behind to 1.5% ahead. This tight grouping shows the RX 7700 XT competes in a narrow performance band. The Rubin GPU, by contrast, has no rivals in the database, reflecting its unique position as a server accelerator without measured competition.

The verdict from the database is straightforward: the RX 7700 XT serves consumers seeking a proven, benchmarked GPU for gaming and general compute, while the Rubin GPU serves server deployments requiring extreme memory bandwidth, tensor throughput, and compute density. The data cannot recommend one over the other for a shared use case because no shared use case exists. The RX 7700 XT is the only part with performance measurements, and the Rubin GPU is the only part with server-class memory and tensor capabilities. Each wins in its own domain, and the database records no crossover.
