AMD Radeon RX 9070 XT vs NVIDIA Tesla K10 Comparison

The Verdict

The NVIDIA Tesla K10 and AMD Radeon RX 9070 XT are separated by more than a decade of GPU architecture, and the benchmark data reflects that gap decisively. The RX 9070 XT wins the only head-to-head benchmark available, the Geekbench OpenCL test, by a margin of 19.5% over the Tesla K10. If you are building a system for modern gaming, content creation, or any compute workload that leverages current APIs, the RX 9070 XT is the only rational choice. The Tesla K10, with its end-of-life production status and 2012 release date, is a legacy compute accelerator with no display outputs, making it unsuitable for any interactive use case.

However, the verdict is not entirely one-sided. The Tesla K10 holds a percentile rank of 55 against all GPUs, identical to the RX 9070 XT's percentile rank of 55. This suggests that in the broader database of GPUs, both cards sit at the same relative position, which is surprising given the generational gap. For a specific niche — legacy compute tasks that rely on Kepler-era CUDA optimizations or dual-GPU configurations — the Tesla K10 might still have a role in a server or research environment. But for virtually every other scenario, the RX 9070 XT's 16 GB of GDDR6 memory, 4096 shading units, and modern RDNA 4.0 architecture make it the superior part. The data shows a clear winner: pick the RX 9070 XT for anything modern, pick the Tesla K10 only if you have a specific legacy requirement.

Architecture Differences

The two GPUs come from entirely different architectural eras. The NVIDIA Tesla K10 is built on the Kepler architecture, using the GK104 chip, and was manufactured on a 28 nm process at TSMC. It packs 3,540 million transistors into a 294 mm² die, yielding a transistor density of 12.0 million transistors per mm². The AMD Radeon RX 9070 XT, in contrast, uses the RDNA 4.0 architecture with the Navi 48 chip, fabricated on a 4 nm process, also at TSMC. It crams 53,900 million transistors into a 357 mm² die, achieving a transistor density of 151.0 million transistors per mm² — a 12.6x improvement in density.

The memory subsystems are radically different. The Tesla K10 has 4 GB of GDDR5 on a 256-bit bus, delivering 160.0 GB/s of bandwidth. The RX 9070 XT has 16 GB of GDDR6 on the same 256-bit bus, but pushes 644.6 GB/s — a 4x increase in both capacity and bandwidth. The RX 9070 XT also features 64 dedicated ray tracing cores, which the Tesla K10 lacks entirely. The API support tells the same story: the Tesla K10 supports DirectX 12 (11_0) and Vulkan 1.2.175, while the RX 9070 XT supports DirectX 12 Ultimate (12_2) and Vulkan 1.4.

Clock speeds also differ dramatically. The Tesla K10 has no listed base or boost clock, but its memory runs at 1250 MHz (5 Gbps effective). The RX 9070 XT runs at a 1660 MHz base clock, 2400 MHz game clock, and 2970 MHz boost clock, with memory at 2518 MHz (20.1 Gbps effective). The compute throughput reflects this: the Tesla K10 delivers 2.289 TFLOPS of FP32 performance, while the RX 9070 XT delivers 48.66 TFLOPS — a 21.3x increase. The RX 9070 XT also matches FP16 at 48.66 TFLOPS (1:1), while the Tesla K10 has no FP16 figure listed.

Head-to-Head Benchmarks

The sole direct comparison in the data is the Geekbench OpenCL test. The AMD Radeon RX 9070 XT scores 17,428, while the NVIDIA Tesla K10 scores 14,029. The RX 9070 XT wins with a delta of -19.5% from the perspective of the Tesla K10, meaning the Tesla K10 trails by 19.5%. This is a significant margin in raw compute performance, but it is importantly the RX 9070 XT's advantage in this single test is not as overwhelming as the architectural differences might suggest. The Tesla K10's OpenCL score of 14,029 places it within 0.9% of the NVIDIA GeForce GTX 680 (14,150) and 1.1% ahead of the AMD Radeon RX 570X (13,871), showing it is still competitive in this specific legacy workload.

The RX 9070 XT's own benchmark suite reveals a broader picture. It scores 65,879 in Geekbench Vulkan, 26,795 in Passmark G3D, and 15,864 in Passmark GPU Compute. These scores indicate strong modern API performance, particularly in Vulkan, which is not available for the Tesla K10 in the data. The RX 9070 XT also shows a 55th percentile ranking against all GPUs, matching the Tesla K10, but its raw scores across multiple tests suggest it is designed for a different workload profile — one that prioritizes current rendering pipelines and compute APIs.

Where Each One Wins

The AMD Radeon RX 9070 XT wins in every modern compute and rendering scenario. Its 16 GB memory buffer is essential for large datasets, high-resolution textures, and AI workloads. The 64 ray tracing cores provide hardware acceleration for ray-traced lighting, which the Tesla K10 cannot do at all. The RX 9070 XT's DirectX 12 Ultimate support enables features like mesh shaders and variable rate shading, while its Vulkan 1.4 support ensures compatibility with current Linux and cross-platform applications. The 48.66 TFLOPS of FP32 and matching FP16 performance make it suitable for machine learning inference and scientific computing that leverages half-precision arithmetic.

The NVIDIA Tesla K10, despite its age, has a few narrow advantages. Its 225 W TDP is lower than the RX 9070 XT's 304 W, making it easier to cool and power in a server chassis. Its dual-slot design and PCIe 3.0 x16 interface are compatible with older server platforms. The Tesla K10's OpenCL score of 14,029 is only 19.5% behind the RX 9070 XT, which is remarkable given the architectural gap, and it remains competitive with cards like the GeForce GTX 680 and Radeon RX 570X. For legacy CUDA applications that were optimized for Kepler-era hardware, the Tesla K10 might still function adequately. However, its end-of-life status, lack of display outputs, and 4 GB memory limit severely constrain its usefulness. The data shows the RX 9070 XT as the winner in 1 out of 1 head-to-head benchmarks, and any builder choosing between these two should select the RX 9070 XT unless they have a very specific, legacy compute requirement.
