AMD Radeon RX 5600 XT vs NVIDIA Tesla K40c Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark recorded in the database is Geekbench OpenCL, and the result is decisively one-sided. The AMD Radeon RX 5600 XT scores 68,537 points, while the NVIDIA Tesla K40c manages 17,468 points. That translates to a 292.4% advantage for the AMD card, meaning the RX 5600 XT delivers nearly four times the compute performance in this specific workload.

This is not a marginal victory. A 292.4% delta represents a generational leap in raw throughput. The Tesla K40c was designed for a different era of professional compute, and the data reflects that. Across the full head-to-head matrix, the AMD card records 1 win, while the Tesla K40c records 0 wins. There is no single benchmark in the database where the NVIDIA card comes out ahead.

Context matters when interpreting this gap. The RX 5600 XT sits at the 66th percentile among all GPUs in the database, while the Tesla K40c sits at the 61st percentile. Their average benchmark scores diverge more sharply: 20,713 for the AMD card versus 17,468 for the Tesla. The percentile difference is modest, but the average score gap of 3,245 points shows that the RX 5600 XT performs consistently better across multiple workloads, not just in the single shared test.

The nearest rivals for each card help frame their respective positions. The RX 5600 XT's closest competitors include the AMD Radeon R9 M390X at 20,662 (0.2% behind), the Intel Arc A750 at 20,582 (0.6% behind), the Intel Arc B570 at 20,556 (0.8% behind), and the NVIDIA GeForce RTX 3070 Mobile at 20,534 (0.9% behind). This cluster of scores within a narrow 1% band indicates the RX 5600 XT is competitively placed among modern mid-range offerings.

The Tesla K40c's nearest rivals tell a different story. The AMD Radeon Pro 460 scores 17,509, just 0.2% ahead. The AMD Radeon Pro 560 scores 17,551, 0.5% ahead. The AMD Radeon 780M scores 17,588, 0.7% ahead. The NVIDIA GeForce RTX 4060 scores 17,639, 1% ahead. All four rivals sit above the Tesla K40c, with the deltas expressed as negative percentages from the Tesla's perspective. This suggests the K40c is at the lower boundary of its performance neighborhood, while the RX 5600 XT sits at the upper boundary of its own.

The Geekbench OpenCL result deserves particular scrutiny because it is the only test both cards share. OpenCL workloads typically stress raw compute throughput, and the RX 5600 XT's much newer architecture and higher clock speeds dominate. The K40c's older Kepler design simply cannot keep pace. The database shows no other overlapping tests, so any broader comparison must rely on the average benchmark scores and percentile rankings, which consistently favor the AMD card.

Architecture Differences

The two cards come from fundamentally different design eras. The AMD Radeon RX 5600 XT uses the Navi 10 chip built on RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. The NVIDIA Tesla K40c uses the GK180 chip built on Kepler architecture, fabricated on a 28 nm process, also at TSMC. The node difference is substantial: 7 nm versus 28 nm.

Transistor counts and die sizes reflect the architectural gap. The Navi 10 packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0M per mm². The GK180 contains 7,080 million transistors spread across a much larger 561 mm² die, resulting in a density of just 12.6M per mm². The RX 5600 XT packs more than three times the transistor density into less than half the silicon area.

Clock speeds diverge sharply. The RX 5600 XT runs at a base clock of 1130 MHz, a game clock of 1375 MHz, and a boost clock of 1560 MHz. The Tesla K40c runs at a base clock of 745 MHz and a boost clock of 876 MHz. The AMD card's boost clock is nearly double the Tesla's base clock, which directly contributes to its compute advantage.

Memory subsystems differ in capacity and type. The RX 5600 XT features 6 GB of GDDR6 on a 192-bit bus with a bandwidth of 288.0 GB/s and a memory clock of 1500 MHz (12 Gbps effective). The Tesla K40c features 12 GB of GDDR5 on a 384-bit bus with a bandwidth of 288.4 GB/s and a memory clock of 1502 MHz (6 Gbps effective). Despite the Tesla having twice the memory capacity and a wider bus, the bandwidth figures are nearly identical, as the newer GDDR6 memory runs at twice the effective speed.

Compute resources are distributed differently. The RX 5600 XT has 2304 shading units, 144 texture mapping units, and 64 raster output units. The Tesla K40c has 2880 shading units, 240 TMUs, and 48 ROPs. The Tesla has more shading units and TMUs, but fewer ROPs. Its pixel rate of 52.56 GPixel/s is well below the RX 5600 XT's 99.84 GPixel/s, and its texture rate of 210.2 GTexel/s trails the AMD card's 224.6 GTexel/s.

Floating-point performance tells a clear story. The RX 5600 XT delivers 7.188 TFLOPS in FP32 and 14.38 TFLOPS in FP16 (2:1 ratio). The Tesla K40c delivers 5.046 TFLOPS in FP32 and has no recorded FP16 capability. The AMD card leads by roughly 42% in FP32 throughput and has a substantial FP16 advantage that the NVIDIA card cannot match at all.

Feature support also diverges. The RX 5600 XT supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Tesla K40c supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The AMD card has a newer DirectX feature level and a newer Vulkan version. The RX 5600 XT uses PCIe 4.0 x16, while the Tesla K40c uses PCIe 3.0 x16. The RX 5600 XT has display outputs (1x HDMI 2.0b and 3x DisplayPort 1.4a), while the Tesla K40c has no display outputs, reflecting its compute-focused design.

The Verdict

The data presents a clear performance hierarchy. The AMD Radeon RX 5600 XT outperforms the NVIDIA Tesla K40c in the only shared benchmark by 292.4%, holds a higher average benchmark score (20,713 versus 17,468), and ranks at a higher percentile (66th versus 61st). The RX 5600 XT also delivers higher FP32 throughput (7.188 TFLOPS versus 5.046 TFLOPS), a higher pixel rate, a higher texture rate, and newer API support.

The Tesla K40c does retain advantages in specific areas: it has 12 GB of memory versus 6 GB, a wider 384-bit memory bus, more shading units (2880 versus 2304), and more TMUs (240 versus 144). It also has a marginally higher memory bandwidth at 288.4 GB/s versus 288.0 GB/s, though this difference is negligible. These specifications do not translate into benchmark victories in the recorded data.

The production status of both cards is end-of-life. The RX 5600 XT was released on 2020-01-20, while the Tesla K40c was released on 2013-10-07. The RX 5600 XT has a launch MSRP of 279 USD, while the Tesla K40c has a launch MSRP of 7,699 USD. The performance data does not justify the Tesla's price premium in any measured workload.

Where Each One Wins

The RX 5600 XT wins in every benchmark category recorded. It dominates in Geekbench OpenCL with a 292.4% margin. Its average benchmark score of 20,713 is 18.6% higher than the Tesla's 17,468. It ranks higher in the overall percentile distribution at 66 versus 61. Its FP32 throughput of 7.188 TFLOPS exceeds the Tesla's 5.046 TFLOPS by roughly 42%. Its pixel rate of 99.84 GPixel/s is nearly double the Tesla's 52.56 GPixel/s. Its texture rate of 224.6 GTexel/s surpasses the Tesla's 210.2 GTexel/s. It offers FP16 compute at 14.38 TFLOPS, which the Tesla cannot provide. It supports newer DirectX (12_1 versus 11_0) and newer Vulkan (1.4 versus 1.2.175) standards. It runs on PCIe 4.0 versus PCIe 3.0. It consumes 150 W versus 245 W and requires a 450 W PSU versus 550 W.

The Tesla K40c wins in narrower, specification-level categories. It has 12 GB of memory versus 6 GB, which could matter for workloads that require large memory footprints. It has a wider 384-bit memory bus versus 192-bit. It has more shading units (2880 versus 2304) and more TMUs (240 versus 144). Its memory bandwidth of 288.4 GB/s is marginally higher, though the difference of 0.4 GB/s is within measurement noise. None of these advantages produce a benchmark victory in the recorded data.

The use-case split is therefore asymmetric. The RX 5600 XT is the stronger choice for general compute, graphics workloads, and any application that relies on FP32 or FP16 throughput. The Tesla K40c's only theoretical advantage lies in scenarios that require more than 6 GB of memory, where its 12 GB capacity could accommodate larger datasets. The database contains no benchmark that demonstrates this advantage in practice.
