NVIDIA GeForce MX550 vs NVIDIA Quadro RTX 8000 Comparison

The NVIDIA Quadro RTX 8000 and the NVIDIA GeForce MX550 are both built on NVIDIA’s Turing architecture, but they occupy opposite ends of the GPU spectrum. The Quadro RTX 8000 is a 48 GB workstation monster designed for professional rendering and compute, while the MX550 is a 25 W laptop part meant for light multimedia acceleration. Benchmark data shows the Quadro RTX 8000 utterly dominates in raw performance, but the MX550 has its place in specific portable, low-power scenarios. This analysis uses only the specification and benchmark data provided to break down exactly where each card stands.

The Verdict

The data is unambiguous: the NVIDIA Quadro RTX 8000 is the choice for anyone needing maximum compute throughput, massive memory capacity, or professional-grade feature sets. In head-to-head benchmarks, it wins both available tests, with a 400.1% lead in Geekbench OpenCL and a 277.7% lead in Geekbench Vulkan over the MX550. Its 48 GB of GDDR6 memory, 4608 shading units, and 16.31 TFLOPS of FP32 performance place it in an entirely different performance class, as reflected by its 74th percentile ranking among all GPUs and an average benchmark score of 28421.

The NVIDIA GeForce MX550, despite having a lower average benchmark score of 26421, still holds a 72nd percentile ranking, which is surprisingly close given the massive gap in raw specs. This is because the MX550’s nearest rivals include the AMD Radeon 860M and the NVIDIA GeForce RTX 5060, indicating it competes in a lower-tier bracket where its 2 GB memory and 2.703 TFLOPS are still relevant. For a user building or buying a thin-and-light laptop where power draw is critical, the MX550’s 25 W TDP and IGP slot width make it the only viable option here; the Quadro RTX 8000’s 260 W TDP and dual-slot design are simply impractical outside a desktop workstation. In short: pick the Quadro RTX 8000 for performance-centric professional work, and the MX550 only if portability and minimal power consumption are non-negotiable.

FAQ

Q: What is the power consumption difference?

A: The Quadro RTX 8000 has a TDP of 260 W and requires a 600 W suggested PSU with 1x 6-pin and 1x 8-pin connectors. The MX550 has a TDP of just 25 W, uses no power connectors, and has no suggested PSU listed.

Q: Which GPU has ray tracing and tensor cores?

A: Only the Quadro RTX 8000 has dedicated hardware for these features, with 72 RT cores and 576 tensor cores. The MX550 has no RT cores and no tensor cores listed.

Architecture Differences

Both GPUs share the same Turing architecture and 12 nm TSMC process node, but their chip designs are profoundly different in scale and capability. The Quadro RTX 8000 is built on the TU102 chip, which contains 18,600 million transistors on a die size of 754 mm², resulting in a transistor density of 24.7M per mm². The MX550 uses the TU117SB chip, with only 4,700 million transistors on a 200 mm² die, for a density of 23.5M per mm². This difference in transistor count explains the massive gap in compute resources.

The Quadro RTX 8000 features 4608 shading units, 288 texture mapping units, and 96 ROPs. It also includes 72 RT cores and 576 tensor cores, which are entirely absent from the MX550’s specification list. The MX550 is limited to 1024 shading units, 32 TMUs, and 16 ROPs. This means the Quadro RTX 8000 can handle hardware-accelerated ray tracing and AI-based tensor operations, while the MX550 relies purely on conventional rasterization. The memory architecture also differs fundamentally: the Quadro RTX 8000 uses a 384-bit bus, while the MX550 uses a 64-bit bus, which severely limits the latter’s memory bandwidth.

Another key architectural difference is in the API support. The Quadro RTX 8000 supports DirectX 12 Ultimate (12_2), which includes features like mesh shaders and variable rate shading, while the MX550 only supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the shader model and feature level differences could matter for specific professional applications.

Specification Differences

The specification sheets show a stark contrast in nearly every field. The Quadro RTX 8000 has base and boost clocks of 1395 MHz and 1770 MHz, respectively, while the MX550 runs at 1065 MHz base and 1320 MHz boost. Memory speed also differs, with the Quadro RTX 8000 at 1750 MHz (14 Gbps effective) versus the MX550 at 1500 MHz (12 Gbps effective). The memory size is the most dramatic difference: 48 GB versus 2 GB of GDDR6.

Compute throughput figures are equally lopsided. The Quadro RTX 8000 achieves 16.31 TFLOPS of FP32 performance and 32.62 TFLOPS of FP16 (2:1 ratio), while the MX550 delivers 2.703 TFLOPS of FP32 and 2.703 TFLOPS of FP16 (1:1 ratio). Pixel rates are 169.9 GPixel/s versus 21.12 GPixel/s, and texture rates are 509.8 GTexel/s versus 42.24 GTexel/s.

Physical and power specifications diverge completely. The Quadro RTX 8000 is a dual-slot card measuring 267 mm in length and 111 mm in height, with a TDP of 260 W and a 600 W suggested PSU. The MX550 is an IGP (integrated graphics processor) with a 25 W TDP, no power connectors, and no physical dimensions listed, as it is designed for portable devices. The bus interface also differs: the Quadro RTX 8000 uses PCIe 3.0 x16, while the MX550 uses PCIe 4.0 x8. Display outputs show the Quadro RTX 8000 with 4x DisplayPort 1.4a and 1x USB Type-C, while the MX550 is listed as "Portable Device Dependent."

Head-to-Head Benchmarks

The only two benchmarks shared between the two GPUs are Geekbench OpenCL and Geekbench Vulkan, and the Quadro RTX 8000 wins both decisively. In Geekbench OpenCL, the Quadro RTX 8000 scores 101883 against the MX550’s 20372, a delta of 400.1%. This means the Quadro RTX 8000 is roughly five times faster in this compute-heavy test, reflecting its 4608 shading units and 672.0 GB/s of memory bandwidth versus the MX550’s 1024 shading units and 96.00 GB/s.

In Geekbench Vulkan, the results are closer in relative terms but still a blowout: 122637 for the Quadro RTX 8000 versus 32469 for the MX550, a 277.7% advantage. Vulkan tests often scale with driver optimization and memory bandwidth, and the Quadro RTX 8000’s larger memory bus and higher clocks give it a clear edge. The MX550 was unable to win either benchmark, resulting in a 2-0 win count for the Quadro RTX 8000.

Looking at broader benchmark context, the Quadro RTX 8000’s average benchmark score is 28421, while the MX550’s is 26421. This difference is smaller than the head-to-head deltas suggest, because the average includes a wider range of tests. The Quadro RTX 8000 also has additional scores in Passmark tests (e.g., G3D score of 19799 and GPU Compute of 9992) that the MX550 lacks, further indicating its superior compute capability. The MX550’s nearest rival, the AMD Radeon 860M, has an average score of 26401, showing it sits in a competitive low-power segment, while the Quadro RTX 8000’s nearest rival, the AMD Radeon R9 M295X, scores 28580, a delta of -0.6%.

Where Each One Wins

The NVIDIA Quadro RTX 8000 wins in every scenario that demands raw compute power, large memory capacity, or professional feature support. Its 48 GB of GDDR6 memory is essential for large dataset workloads like 3D rendering, scientific simulation, or machine learning inference, where 2 GB would be immediately exhausted. The 72 RT cores and 576 tensor cores enable hardware-accelerated ray tracing and AI-accelerated workflows, which the MX550 cannot handle at all. The Quadro RTX 8000’s 16.31 TFLOPS of FP32 performance and 672.0 GB/s bandwidth make it a winner for compute-heavy applications, as evidenced by its 400.1% lead in OpenCL. Its support for DirectX 12 Ultimate also gives it a future-proofing advantage for professional visualization tools that leverage the latest API features.

The NVIDIA GeForce MX550 wins in the niche of ultra-low-power, portable computing. With a 25 W TDP and IGP form factor, it can be integrated into thin laptops without dedicated power connectors or a bulky cooler. Its 2 GB of GDDR6 memory and 2.703 TFLOPS are sufficient for basic video playback, light photo editing, or casual gaming at modest resolutions. The MX550’s 72nd percentile ranking shows it performs competitively against other low-power parts like the AMD Radeon 860M, and its PCIe 4.0 x8 interface offers faster data transfer than the older PCIe 3.0 on the Quadro RTX 8000. For a user who prioritizes battery life and portability over performance, the MX550 is the only sensible choice between these two. The Quadro RTX 8000’s 260 W TDP and dual-slot design are simply incompatible with any portable chassis.
