AMD Radeon RX 5700 XT vs NVIDIA Quadro K6000 Comparison

Head-to-Head Benchmarks

The recorded data shows a stark split between these two cards depending on the API and workload. In Geekbench Metal, the AMD Radeon RX 5700 XT delivers a score of 74,647, which is 89.4% ahead of the NVIDIA Quadro K6000's 7,932. This is the largest margin in any shared test, and it reflects a generational leap in GPU compute and driver maturity for Apple's Metal framework. The K6000's score here is not just lower, it is in a different performance class entirely, making the RX 5700 XT the clear choice for Metal-centric applications.

The tables turn completely in Geekbench OpenCL. The Quadro K6000 posts 23,749, while the RX 5700 XT manages only 9,524. That gives NVIDIA a 149.4% advantage, the single biggest win for either card in the head-to-head dataset. This is a surprising result given the RX 5700 XT's newer architecture and higher raw FP32 throughput, but the data is unambiguous: in this specific OpenCL workload, the older Kepler card dominates.

Geekbench Vulkan shows a more moderate but still decisive win for AMD. The RX 5700 XT scores 68,310 versus 25,409 for the K6000, a 62.8% margin. Vulkan is a modern low-level API, and the RDNA 1.0 architecture handles it far more efficiently than Kepler, which was designed before Vulkan existed. Across the three shared benchmarks, AMD wins two and NVIDIA wins one, but the magnitude of the wins matters: AMD's Metal and Vulkan victories are crushing, while NVIDIA's OpenCL win is equally emphatic in the opposite direction.

FAQ

Q: Which card has the higher average benchmark score?

A: The NVIDIA Quadro K6000 has an average benchmark score of 19,030, placing it in the 63rd percentile of all GPUs. The AMD Radeon RX 5700 XT has an average score of 16,361, placing it in the 59th percentile. Despite losing two of the three head-to-head tests, the K6000's overall average is higher because its OpenCL score is so strong and its Vulkan score, while lower than AMD's, is not catastrophic.

Q: How does the Quadro K6000 compare to its nearest rivals?

A: The K6000's average score of 19,030 is nearly identical to the AMD Radeon RX 6600 at 19,036, a 0% difference. It is 0.1% behind the NVIDIA GeForce RTX 4050 Mobile (19,049), 0.3% behind the NVIDIA Tesla K20m (19,089), and 0.4% ahead of the NVIDIA RTX 2000 Ada Generation (18,954). This puts the K6000 in a tight cluster of mid-range performers despite its age.

Q: Where does the RX 5700 XT sit among its nearest rivals?

A: The Quadro K6000 has 12 GB of GDDR5 on a 384-bit bus, yielding 288.4 GB/s of bandwidth. The RX 5700 XT has 8 GB of GDDR6 on a 256-bit bus, yielding 448.0 GB/s. AMD has less capacity but significantly more bandwidth, which favors high-resolution textures and compute workloads that stream data heavily.

Q: Does the RX 5700 XT support newer APIs?

A: Yes. The RX 5700 XT supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Quadro K6000 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.175. The K6000's DirectX support is limited to feature level 11_1, meaning it cannot use the full DirectX 12 feature set that the RX 5700 XT can.

Architecture Differences

The two cards are separated by six years of GPU design philosophy. The Quadro K6000 uses the GK110B chip on NVIDIA's Kepler architecture, built on a 28 nm process at TSMC with 7,080 million transistors on a 561 mm² die. That works out to a transistor density of 12.6 million per square millimeter. Kepler was designed for compute-heavy professional workloads, with 2,880 shading units, 240 texture mapping units, and 48 raster output units. Its pixel rate is 54.12 GPixel/s, its texture rate is 216.5 GTexel/s, and its FP32 throughput is 5.196 TFLOPS.

The RX 5700 XT uses the Navi 10 chip on AMD's RDNA 1.0 architecture, built on a 7 nm process at the same foundry, TSMC. It packs 10,300 million transistors into just 251 mm², giving a transistor density of 41.0 million per square millimeter, more than three times the K6000's density. RDNA 1.0 is a gaming-first architecture with 2,560 shading units, 160 TMUs, and 64 ROPs. Its pixel rate is 121.9 GPixel/s, its texture rate is 304.8 GTexel/s, and its FP32 throughput is 9.754 TFLOPS. It also has FP16 support at 19.51 TFLOPS with a 2:1 ratio, which the K6000 completely lacks in the recorded data.

The architectural differences explain the benchmark results. Kepler's OpenCL performance is legendary because it was designed for GPGPU compute in workstations, and the K6000's 149.4% OpenCL victory reflects that heritage. RDNA 1.0, by contrast, was optimized for gaming and modern APIs like Vulkan and Metal, which is why it leads by 62.8% and 89.4% respectively in those tests. The transistor density gap also tells the story: AMD crams nearly three times more transistors per square millimeter, allowing higher clocks and better efficiency despite the older process node limitations being irrelevant here since both use TSMC.

Neither card has ray tracing cores or tensor cores in the recorded data, so both rely on traditional rasterization and compute units. The K6000's huge die area and high transistor count were a marvel in 2013, but the RX 5700 XT achieves comparable or better results in most modern workloads with a fraction of the silicon area. The FP32 gap is nearly double in AMD's favor, yet the K6000 still wins in OpenCL, which suggests driver optimization and compute scheduling differences matter more than raw FLOPs in that specific test.

Specification Differences

The process node differs significantly: the Quadro K6000 uses 28 nm, while the RX 5700 XT uses 7 nm. Transistor count is 7,080 million for NVIDIA versus 10,300 million for AMD. Die size is 561 mm² for the K6000 versus 251 mm² for the RX 5700 XT, and transistor density is 12.6 million per mm² versus 41.0 million per mm².

Clock speeds are radically different. The K6000 has a base clock of 797 MHz and a boost clock of 902 MHz. The RX 5700 XT has a base clock of 1,605 MHz, a game clock of 1,755 MHz, and a boost clock of 1,905 MHz. Memory clocks also differ: the K6000 runs at 1,502 MHz with 6 Gbps effective, while the RX 5700 XT runs at 1,750 MHz with 14 Gbps effective.

Memory capacity is 12 GB of GDDR5 for the K6000 versus 8 GB of GDDR6 for the RX 5700 XT. Bus width is 384-bit versus 256-bit. Bandwidth is 288.4 GB/s versus 448.0 GB/s. Shading units are 2,880 versus 2,560. TMUs are 240 versus 160. ROPs are 48 versus 64. Pixel rate is 54.12 GPixel/s versus 121.9 GPixel/s. Texture rate is 216.5 GTexel/s versus 304.8 GTexel/s. FP32 is 5.196 TFLOPS versus 9.754 TFLOPS. FP16 is absent on the K6000 and 19.51 TFLOPS on the RX 5700 XT.

Both cards have a TDP of 225 W and a suggested PSU of 550 W. Both are dual-slot designs. The K6000 uses 2x 6-pin power connectors, while the RX 5700 XT uses 1x 6-pin plus 1x 8-pin. The K6000 is 267 mm long and 111 mm tall. The RX 5700 XT is 272 mm long, 111 mm tall, and 36 mm wide. The K6000 uses PCIe 3.0 x16, while the RX 5700 XT uses PCIe 4.0 x16. Display outputs are 2x DVI and 2x DisplayPort 1.2 for NVIDIA, versus 1x HDMI 2.0b and 3x DisplayPort 1.4a for AMD. DirectX support is 12 (11_1) versus 12 (12_1). Vulkan support is 1.2.175 versus 1.4. OpenGL is 4.6 for both.

Where Each One Wins

The Quadro K6000 wins decisively in OpenCL compute, with a 149.4% lead over the RX 5700 XT in Geekbench OpenCL. This makes it the better choice for workloads that rely heavily on OpenCL, such as certain scientific computing, video processing, and professional rendering pipelines that have not migrated to Vulkan or Metal. Its 12 GB of VRAM is also an advantage for large datasets that exceed the RX 5700 XT's 8 GB capacity, even though the bandwidth is lower. The K6000's dual DVI outputs also make it suitable for legacy display setups that require DVI connections.

The RX 5700 XT wins in every modern graphics API tested. It leads by 89.4% in Geekbench Metal, making it the obvious pick for macOS or iOS development environments, and by 62.8% in Geekbench Vulkan, which covers most modern Linux and Windows gaming and compute applications. Its higher pixel rate, texture rate, and FP32 throughput translate directly to better rasterization performance in games and real-time graphics. The 448.0 GB/s memory bandwidth is nearly 56% higher than the K6000's, which helps with high-resolution textures and bandwidth-sensitive compute. It also has modern display outputs with HDMI 2.0b and DisplayPort 1.4a, supporting higher refresh rates and newer monitors.

The K6000's higher average benchmark score of 19,030 versus 16,361 for the RX 5700 XT is notable, but it is driven entirely by the OpenCL outlier. In practical terms, the RX 5700 XT is the better all-rounder for contemporary workloads, while the K6000 is a specialist tool for OpenCL-heavy tasks and large VRAM footprints.

The Verdict

The data presents a clear split based on use case. For anyone working in OpenCL-centric professional environments, the NVIDIA Quadro K6000 is the better card. Its 149.4% lead in Geekbench OpenCL is overwhelming, and its 12 GB of VRAM provides headroom for memory-hungry datasets that would choke an 8 GB card. The K6000's average benchmark score of 19,030 also places it in the 63rd percentile of all GPUs, ahead of the RX 5700 XT's 59th percentile and 16,361 average. Its nearest rivals include the AMD Radeon RX 6600 and NVIDIA GeForce RTX 4050 Mobile, all within a 0.4% band, which means it still competes with modern mid-range hardware in aggregate performance.

For gaming, modern API development, or any workload that touches Vulkan or Metal, the AMD Radeon RX 5700 XT is the only rational choice. Its 89.4% Metal lead and 62.8% Vulkan lead are not small margins; they are generational gaps. The RX 5700 XT also offers higher clocks, double the transistor density, significantly more memory bandwidth, and support for newer DirectX and Vulkan feature levels. Its nearest rivals include the RTX PRO 6000 Blackwell and GeForce RTX 5090 D V2, which shows it sits near much newer and more expensive hardware in average score, despite being end-of-life.

There is no single winner across all metrics. The K6000 wins the average-score comparison and the OpenCL test, while the RX 5700 XT wins the two modern API tests by massive margins. The verdict depends entirely on the software stack. If OpenCL is your primary API and you need 12 GB of VRAM, the K6000 remains viable. If you touch any modern graphics workload, the RX 5700 XT is the clear pick. The recorded data does not support a universal recommendation; it supports a workload-specific one.
