AMD Radeon RX 6500 XT vs NVIDIA Tesla K10 Comparison

The NVIDIA Tesla K10 and the AMD Radeon RX 6500 XT occupy very different corners of the GPU landscape. The Tesla K10 is a compute-oriented accelerator from 2012, built for professional workloads, while the RX 6500 XT is a modern consumer graphics card from 2022. The recorded data shows they are closely matched in overall percentile standing, with the K10 at the 55th percentile of all GPUs and the RX 6500 XT at the 51st. Yet their benchmark results diverge dramatically, and the specifications tell a story of two completely different design philosophies.

Where Each One Wins

The AMD Radeon RX 6500 XT wins the only direct head-to-head benchmark recorded in the database. In the Geekbench OpenCL test, the RX 6500 XT scores 48,289, while the Tesla K10 scores 14,029. That is a difference of 70.9% in favor of the AMD card, meaning the RX 6500 XT delivers roughly three and a half times the raw compute performance in this particular workload. The K10 does not win any recorded benchmark in this comparison, so the use-case split is sharply one-sided based on the available data.

However, the two cards were built for different purposes. The Tesla K10 has no display outputs, which means it cannot drive a monitor at all. It is designed strictly for server or workstation compute tasks where rendering to a screen is unnecessary. The RX 6500 XT includes 1x HDMI 2.1 and 1x DisplayPort 1.4a outputs, making it a functional consumer card for gaming and desktop use. The data implies that the RX 6500 XT is the clear choice for any task involving graphics output or general-purpose compute, while the Tesla K10 would only be relevant in a headless compute environment, and even then it trails badly in the one benchmark recorded.

Head-to-Head Benchmarks

The single recorded head-to-head benchmark is Geekbench OpenCL, and it is a landslide. The RX 6500 XT scores 48,289, and the Tesla K10 scores 14,029. The percentage difference is 70.9%, which means the RX 6500 XT is more than three times faster in this test. This is especially striking given the hardware differences. The Tesla K10 has 1,536 shading units and 128 texture mapping units, while the RX 6500 XT has only 1,024 shading units and 64 texture mapping units. The K10 has more of both, yet it cannot translate that into compute performance.

The clock speeds explain part of the gap. The Tesla K10 has no recorded base or boost clock, but its memory runs at 1250 MHz with 5 Gbps effective speed. The RX 6500 XT has a base clock of 2310 MHz, a game clock of 2610 MHz, and a boost clock of 2815 MHz. Its memory runs at 2248 MHz with 18 Gbps effective speed. The RX 6500 XT also has a much higher pixel rate at 90.08 GPixel/s versus 23.84 GPixel/s for the K10, and a texture rate of 180.2 GTexel/s versus 95.36 GTexel/s. The FP32 throughput is 5.765 TFLOPS for the RX 6500 XT versus 2.289 TFLOPS for the K10. Every throughput metric favors the AMD card, and the benchmark reflects that.

The nearest rival data reinforces the point. The Tesla K10 has an average score of 14,029, which places it near the GeForce GTX 680 at 14,150 and the Radeon RX 570X at 13,871. The RX 6500 XT has an average score of 11,842, placing it near the GeForce GTX 1080 at 11,960 and the GeForce GTX 960A at 11,998. Interestingly, the K10 has the higher average score, yet the RX 6500 XT wins the OpenCL test by a wide margin. This suggests the K10 may perform better in other unrecorded workloads, while the RX 6500 XT is particularly strong in OpenCL compute.

Specification Differences

The two cards differ in nearly every major specification category. The Tesla K10 uses 4 GB of GDDR5 memory on a 256-bit bus, delivering 160.0 GB/s of bandwidth. The RX 6500 XT also has 4 GB of memory, but it uses GDDR6 on a 64-bit bus, delivering 143.9 GB/s. Despite the narrower bus, the RX 6500 XT achieves close to the same bandwidth due to its much faster memory clock.

The process nodes are generations apart. The Tesla K10 is built on a 28 nm process at TSMC, with 3,540 million transistors on a 294 mm² die. The RX 6500 XT is built on a 6 nm process, also at TSMC, with 5,400 million transistors on a much smaller 107 mm² die. The transistor density tells the story: the K10 has 12.0 million transistors per square millimeter, while the RX 6500 XT has 50.5 million per square millimeter. The newer process allows the RX 6500 XT to pack more transistors into less space while drawing far less power.

Power consumption is another major divider. The Tesla K10 has a TDP of 225 W and requires a 550 W power supply, using 1x 6-pin and 1x 8-pin power connectors. The RX 6500 XT has a TDP of 107 W, requires only a 300 W power supply, and uses a single 6-pin connector. The RX 6500 XT delivers more performance while consuming less than half the power, a direct result of the architecture and process improvements.

The bus interfaces differ as well. The Tesla K10 uses PCIe 3.0 x16, while the RX 6500 XT uses PCIe 4.0 x4. The RX 6500 XT also supports newer API standards, including DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the K10 is limited to DirectX 12 (11_0) and Vulkan 1.2.175. Display outputs are exclusive to the RX 6500 XT, as the Tesla K10 has none.

Architecture Differences

The architectural gap between these two GPUs spans a decade of development. The Tesla K10 is based on the Kepler architecture, using the GK104 chip, and belongs to the Tesla Kepler generation. The RX 6500 XT is based on RDNA 2.0, using the Navi 24 chip, and belongs to the Navi II generation within the RX 6000 series. The K10's predecessor is Tesla Fermi and its successor is Tesla Maxwell. The RX 6500 XT's predecessor is Navi and its successor is Navi III.

The core configurations reflect different design priorities. The Tesla K10 has 1,536 shading units, 128 TMUs, and 32 ROPs. The RX 6500 XT has 1,024 shading units, 64 TMUs, and 32 ROPs. The K10 has more shading units and double the TMUs, but the RX 6500 XT compensates with much higher clock speeds and a more efficient architecture. The RX 6500 XT also includes 16 ray tracing cores, a feature entirely absent from the Kepler-based K10.

Memory technology also differs fundamentally. The K10 uses GDDR5, while the RX 6500 XT uses GDDR6. The RX 6500 XT has a lower bus width of 64 bits versus 256 bits, but its faster memory clock and newer technology keep bandwidth competitive at 143.9 GB/s versus 160.0 GB/s. The RX 6500 XT also supports FP16 computation at 11.53 TFLOPS with a 2:1 ratio, while the K10 has no recorded FP16 performance.

The release dates show the generational gap clearly. The Tesla K10 was released on 2012-04-30, and the RX 6500 XT was released on 2022-01-18. Both are now marked as end-of-life in the database. The Tesla K10 had a launch MSRP of 5,099 USD, while the RX 6500 XT had a launch MSRP of 199 USD. Physical dimensions differ too: the Tesla K10 is 272 mm long, while the RX 6500 XT has no recorded length in the database.

The Verdict

The data points to one clear conclusion for almost any use case: the AMD Radeon RX 6500 XT is the superior GPU. It wins the only recorded head-to-head benchmark by 70.9%, offers modern API support including DirectX 12 Ultimate and Vulkan 1.4, includes ray tracing hardware, has display outputs, and consumes 107 W versus the Tesla K10's 225 W. The RX 6500 XT also delivers higher pixel rate, texture rate, and FP32 throughput despite having fewer shading units and TMUs. Its 6 nm process and RDNA 2.0 architecture give it a decisive efficiency and feature advantage.

The NVIDIA Tesla K10 has one statistical edge: its average benchmark score of 14,029 is higher than the RX 6500 XT's 11,842. But this average is based on a single OpenCL result, and in that very same test the RX 6500 XT scores 48,289. The K10 also has more shading units, a wider 256-bit memory bus, and higher memory bandwidth, but these advantages do not translate into winning performance in the recorded data. The K10's lack of display outputs and its 2012-era Kepler architecture make it a poor choice for any modern workload.

For anyone building a system today, the RX 6500 XT is the only sensible pick from these two options. It supports modern graphics APIs, runs on a 300 W power supply, and fits in a dual-slot form factor with a single 6-pin connector. The Tesla K10 requires a 550 W power supply, dual power connectors, and offers no way to connect a monitor. The benchmark data confirms what the specifications suggest: the RX 6500 XT is faster, more efficient, and far more capable in every measurable way. The only scenario where the K10 might be considered is a legacy compute deployment that specifically requires Kepler architecture, but even then its performance is severely limited compared to the RX 6500 XT.
