Intel Arc A550M vs NVIDIA Quadro M6000 Comparison

The benchmark data presents a clear generational clash: Intel’s Arc A550M, a mobile-first Alchemist part, squares off against NVIDIA’s Quadro M6000, a professional workstation card from the Maxwell era. Across the two recorded Geekbench tests, the Intel part wins both, but the margin and the underlying architectural context tell a more nuanced story than a simple sweep. The Arc A550M achieves an average benchmark score of 49,737, placing it in the 86th percentile of all GPUs, while the Quadro M6000 averages 43,301, sitting in the 84th percentile. These percentile figures are close, yet the raw score gap of 6,436 points represents a meaningful performance tier separation in compute workloads.

Head-to-Head Benchmarks

The most decisive victory for the Intel Arc A550M comes in the Geekbench OpenCL test. Here, the Arc scores 49,894 against the Quadro M6000’s 39,688, a delta of 25.7% in Intel’s favor. This is a substantial lead, indicating that the Arc’s modern architecture delivers significantly higher raw compute throughput in this API. The Quadro’s Maxwell architecture, while competent in its day, is simply outmatched by the sheer shader count and clock speed advantages of the newer part. The Arc’s FP32 throughput of 8.397 TFLOPS compared to the Quadro’s 6.844 TFLOPS aligns with this result, though the benchmark delta is larger than the theoretical peak would suggest, pointing to efficiency gains beyond raw specs.

The Vulkan test is much closer. The Arc A550M scores 49,580, while the Quadro M6000 posts 46,913, yielding a narrower 5.7% advantage for Intel. This reduced margin suggests that the Quadro’s driver maturity and Maxwell’s strong geometry processing keep it competitive in a lower-level API. Notably, the Quadro’s Vulkan score of 46,913 is actually higher than its OpenCL score of 39,688, a reverse pattern from the Arc, which scores nearly identically across both APIs (49,894 vs. 49,580). This difference implies the Arc’s performance is consistent regardless of API, whereas the Quadro shows API-specific strengths. The data shows the Arc wins both tests, but the Vulkan result indicates the Quadro is not a pushover in every workload.

Looking at the broader rival landscape, the Arc A550M’s average score of 49,737 places it within a tight cluster of high-end cards. It trails the AMD Radeon RX Vega 64 (50,001) by just 0.5% and the AMD Radeon RX 6900 XT (50,951) by 2.4%, while leading the AMD Radeon RX 6800 XT (48,477) by 2.6%. The Quadro M6000’s average of 43,301 sits in a different performance tier, matching the NVIDIA GeForce RTX 5050 Mobile (43,268) within 0.1% and the NVIDIA GeForce RTX 4070 SUPER (43,223) within 0.2%. It trails the NVIDIA GeForce RTX 4090 Mobile (43,667) by 0.8%. This contextual data shows the Arc competing with enthusiast-class gaming GPUs from a few generations back, while the Quadro aligns with modern mid-range mobile parts, despite being a desktop workstation card.

Q: Which GPU has better raw compute specifications?

A: The Arc A550M leads in FP32 throughput with 8.397 TFLOPS versus the Quadro’s 6.844 TFLOPS. The Arc also has a higher boost clock at 2050 MHz versus 1114 MHz, and a smaller process node at 6 nm versus 28 nm.

Architecture Differences

The architectural divide between these two GPUs is vast, reflecting nearly a decade of semiconductor evolution. The Intel Arc A550M is built on the Xe-HPG architecture, specifically the DG2-512 chip, fabricated on a 6 nm process at TSMC. This modern node packs 21,700 million transistors into a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. In contrast, the NVIDIA Quadro M6000 uses the Maxwell 2.0 architecture with the GM200 chip, built on a 28 nm process, also at TSMC. This older node contains only 8,000 million transistors across a larger 601 mm² die, resulting in a much lower density of 13.3 million per square millimeter.

The Arc A550M features 16 dedicated ray tracing cores, a technology entirely absent from the Quadro M6000, which has no RT cores. This makes the Arc compatible with DirectX 12 Ultimate (12_2), while the Quadro is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the feature set under the hood is fundamentally different. The Arc also supports FP16 computation at a 2:1 ratio, delivering 16.79 TFLOPS, while the Quadro has no listed FP16 capability, meaning it likely processes such workloads at reduced throughput or emulation. The Arc’s memory is GDDR6 running at 14 Gbps effective, while the Quadro uses GDDR5 at 6.6 Gbps effective. These are different memory generations with distinct latency and power characteristics.

The shader configuration also differs significantly. The Arc has 2048 shading units, 128 texture mapping units, and 64 raster output units. The Quadro has more of each: 3072 shading units, 192 TMUs, and 96 ROPs. However, the Arc compensates with much higher clocks — a 900 MHz base and 2050 MHz boost versus the Quadro’s 988 MHz base and 1114 MHz boost. This clock advantage, combined with the newer architecture’s efficiency, allows the Arc to achieve higher pixel and texture rates: 131.2 GPixel/s and 262.4 GTexel/s versus the Quadro’s 106.9 GPixel/s and 213.9 GTexel/s. The Quadro’s higher raw unit counts cannot overcome its clock disadvantage.

Specification Differences

The specification sheets reveal distinct design philosophies. The Intel Arc A550M is a mobile-oriented part with a 60 W TDP, designed as an IGP (integrated graphics processor) solution with no separate slot width or power connectors. Its bus interface is PCIe 4.0 x16, and its display outputs are listed as "Portable Device Dependent," meaning connectivity varies by laptop implementation. The Quadro M6000, by contrast, is a desktop workstation card with a 250 W TDP, a dual-slot form factor, a single 8-pin power connector, and a suggested 600 W power supply. It uses PCIe 3.0 x16 and offers fixed display outputs: 1x DVI and 4x DisplayPort 1.2.

Memory configurations differ sharply. The Arc has 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The Quadro has 12 GB of GDDR5 on a 384-bit bus, yielding 317.4 GB/s. This means the Quadro offers 50% more memory capacity and roughly 42% more bandwidth, which could benefit large dataset workloads. However, the Arc’s newer memory type operates at a higher effective clock (14 Gbps vs. 6.6 Gbps), partially offsetting the bus width disadvantage. The Quadro’s physical dimensions are 267 mm in length and 111 mm in height, while the Arc has no listed dimensions due to its IGP nature. The Quadro’s release date is March 20, 2015, with a predecessor of Quadro Kepler and a successor of Quadro Pascal; the Arc has no listed release date, predecessor, or successor.

The Verdict

The data points to a clear but context-dependent recommendation. The Intel Arc A550M is the faster GPU in both recorded benchmarks, winning OpenCL by 25.7% and Vulkan by 5.7%. Its average score of 49,737 places it in the 86th percentile, significantly ahead of the Quadro’s 43,301 and 84th percentile. If the priority is raw compute performance in OpenCL or consistent performance across APIs, the Arc is the obvious choice. Its modern architecture, ray tracing support, and FP16 capability make it a forward-looking part, despite its end-of-life status.

The Quadro M6000, however, is not without merit for specific use cases. Its 12 GB of memory and 384-bit bus provide higher capacity and bandwidth, which could be advantageous for memory-bound professional workloads. Its Vulkan score of 46,913 shows it remains competitive in that API, trailing the Arc by only 5.7%. For users constrained to legacy PCIe 3.0 platforms or requiring fixed workstation display outputs (DVI and DisplayPort 1.2), the Quadro offers a known quantity. It matches modern mid-range GPUs like the RTX 5050 Mobile and RTX 4070 SUPER in average score, indicating it still holds its own in current benchmarks.

The choice ultimately hinges on workload type. The Arc A550M is the superior compute part, with higher TFLOPS, faster clocks, and a massive transistor density advantage. The Quadro M6000 offers more memory and bandwidth, making it potentially better for large frame buffers or datasets. Given that the Arc wins both head-to-head tests and holds a higher percentile ranking, the benchmark data favors it for general performance. The Quadro’s edge in memory capacity is its only clear specification advantage, and that alone does not overcome the Arc’s compute lead in the recorded tests. For most users seeking performance, the Arc A550M is the data-backed recommendation.
