Intel Arc B570 vs NVIDIA Quadro K6000 Comparison

The Intel Arc B570 and NVIDIA Quadro K6000 represent two distinct eras of GPU design, separated by more than a decade of architectural evolution. The benchmark data shows a decisive performance shift toward the modern Intel part, but the Quadro K6000 retains specific strengths in memory capacity that may matter for specialized workloads. This analysis compares the two based strictly on measured results and documented specifications.

Head-to-Head Benchmarks

The direct comparison between these two cards is limited to two shared benchmark tests, and the results are overwhelmingly in favor of the Intel Arc B570. In the Geekbench OpenCL test, the Arc B570 scores 83,514 points against the Quadro K6000's 23,749 points. This represents a delta of 251.7% — the Intel card delivers more than three and a half times the compute throughput in this API. The margin is even larger in the Geekbench Vulkan test, where the Arc B570 posts 96,844 points versus 25,409 points for the Quadro K6000, a delta of 281.1%.

These are not marginal improvements; they are generational leaps. The Quadro K6000, built on the Kepler architecture from 2013, simply cannot compete with the Xe2-HPG architecture's modern execution units in these cross-platform compute tests. The OpenCL result is particularly telling because it reflects raw shader throughput and driver efficiency. The Arc B570's 11.52 TFLOPS of FP32 performance versus the Quadro K6000's 5.196 TFLOPS explains much of this gap — more than double the theoretical compute ceiling, and the benchmark results confirm that theoretical advantage translates to real-world execution.

The Vulkan delta of 281.1% is even more pronounced, suggesting that the Arc B570's architecture handles modern graphics API workloads with far greater efficiency. The Quadro K6000 supports Vulkan 1.2.175, but its Kepler cores were designed before that API existed. The Intel card's native support for Vulkan 1.4, combined with its newer shader design, produces results that are nearly four times faster.

Looking at the broader benchmark context, the Arc B570 holds an average benchmark score of 20,556 across all its tested workloads, placing it at the 65th percentile of all GPUs. Its nearest rival is the NVIDIA GeForce RTX 3070 Mobile, which scores 20,534 (a delta of 0.1%), and it sits just ahead of the Intel Arc A750 at 20,582 (delta -0.1%). The Quadro K6000, by contrast, averages 19,030 across its benchmark suite, landing at the 63rd percentile. Its closest competitor is the AMD Radeon RX 6600 at 19,036 (delta 0%), and it edges out the NVIDIA GeForce RTX 4050 Mobile at 19,049 (delta -0.1%).

While the Arc B570's average score is only about 8% higher than the Quadro K6000's, this aggregate figure masks the enormous disparity in modern API tests. The averages include different workload mixes — the Arc B570 has Passmark results for DirectX 9 through 12 and GPU compute, while the Quadro K6000 only has Geekbench Metal, OpenCL, and Vulkan scores. The head-to-head comparisons are the most reliable indicator, and they show a 2-0 win tally for the Intel card.

Architecture Differences

The fundamental divide between these GPUs is architectural. The Intel Arc B570 uses the BMG-G21 chip built on TSMC's 5 nm process, featuring 19,600 million transistors on a 272 mm² die. The NVIDIA Quadro K6000 uses the GK110B chip on a 28 nm process, with 7,080 million transistors on a much larger 561 mm² die. The transistor density difference is stark: 72.1 million transistors per mm² for the Intel part versus 12.6 million per mm² for the NVIDIA part. This explains how Intel packs nearly three times the transistors into half the silicon area.

The core configurations also diverge significantly. The Arc B570 houses 2,304 shading units, 144 texture mapping units, and 80 render output units. It also includes 18 dedicated ray tracing cores, a feature the Quadro K6000 lacks entirely. The Kepler-based NVIDIA card has 2,880 shading units, 240 TMUs, and 48 ROPs — more shaders and TMUs, but far fewer ROPs. Despite having fewer shading units, the Arc B570 achieves higher pixel and texture throughput: 200.0 GPixel/s and 360.0 GTexel/s versus 54.12 GPixel/s and 216.5 GTexel/s for the Quadro K6000. The clock speed difference drives this — the Arc B570 runs at 2500 MHz base and boost, while the Quadro K6000 runs at 797 MHz base and 902 MHz boost.

Memory architecture represents another major divergence. The Arc B570 uses 10 GB of GDDR6 on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The Quadro K6000 uses 12 GB of GDDR5 on a 384-bit bus, but its bandwidth is lower at 288.4 GB/s. The newer GDDR6 memory operates at 2375 MHz (19 Gbps effective) compared to the GDDR5's 1502 MHz (6 Gbps effective). The Intel card compensates for its narrower bus with significantly faster memory clocks, resulting in 31.8% more bandwidth despite having 2 GB less capacity.

The feature sets reflect their respective eras. The Arc B570 supports DirectX 12 Ultimate (12_2), while the Quadro K6000 only reaches DirectX 12 (11_1). Both support OpenGL 4.6, but the Arc B570 supports Vulkan 1.4 versus the Quadro's 1.2.175. The Intel card also has dedicated ray tracing hardware, which the Kepler architecture predates. The Arc B570 offers modern display outputs — 1x HDMI 2.1a and 3x DisplayPort 2.1 — while the Quadro K6000 provides 2x DVI and 2x DisplayPort 1.2, reflecting its professional workstation origins from 2013.

Power characteristics also differ meaningfully. The Arc B570 draws 150 W TDP and requires a single 8-pin power connector with a suggested 450 W PSU. The Quadro K6000 draws 225 W TDP and needs two 6-pin connectors with a suggested 550 W PSU. The Intel card delivers far more performance while consuming 33% less power — a direct consequence of the 5 nm process versus 28 nm.

The Verdict

The data points to a clear conclusion: the Intel Arc B570 is the superior GPU for nearly every measurable workload. Its 251.7% lead in OpenCL and 281.1% lead in Vulkan represent overwhelming advantages in modern compute and graphics APIs. The architecture gap is simply too large to overcome — a 5 nm design from 2025 versus a 28 nm design from 2013.

The Quadro K6000's only quantitative advantage is its 12 GB memory capacity versus 10 GB. For workloads that require more than 10 GB of framebuffer, the Quadro might be the only choice between these two. However, that capacity comes with lower bandwidth (288.4 GB/s versus 380.0 GB/s), which would limit its effective performance in memory-intensive scenarios.

For users prioritizing compute performance, modern API support, ray tracing capability, or power efficiency, the Arc B570 is the data-backed choice. Its 150 W TDP versus 225 W, its DirectX 12 Ultimate support, and its dedicated ray tracing cores all align with modern software requirements. The Quadro K6000, now end-of-life with a production status marked as such, retains relevance only for legacy applications that demand its specific memory configuration or its older display outputs (2x DVI).

The percentile rankings reinforce this. The Arc B570 sits at the 65th percentile of all GPUs, while the Quadro K6000 sits at the 63rd. The gap in average benchmark scores (20,556 versus 19,030) is modest, but the head-to-head tests show that the Intel card's strengths are precisely in the areas where modern software is moving. The Quadro K6000's era has passed; the benchmark data shows no scenario where its architectural approach yields a competitive advantage beyond raw memory size.
