AMD Radeon Pro 5300 vs NVIDIA CMP 50HX Comparison

Head-to-Head Benchmarks

The benchmark data is decisive: NVIDIA CMP 50HX wins both recorded head-to-head tests outright, with no tests favoring AMD Radeon Pro 5300. The largest margin comes in Geekbench OpenCL, where NVIDIA CMP 50HX scores 56,135 against AMD Radeon Pro 5300's 38,747. That is a 44.9% advantage, a massive gap that places the NVIDIA card in a different performance class entirely. In Geekbench Vulkan, NVIDIA CMP 50HX again leads, posting 47,445 versus 35,793, a 32.6% delta. Both victories are substantial, and neither is a close call. The data shows a consistent pattern: NVIDIA CMP 50HX outperforms AMD Radeon Pro 5300 by roughly a third to nearly half depending on the API.

Looking at average benchmark scores across the database, NVIDIA CMP 50HX records 51,790, while AMD Radeon Pro 5300 sits at 40,870. That represents a 26.7% gap in favor of NVIDIA. The percentile rankings reinforce this: NVIDIA CMP 50HX lands in the 86th percentile of all GPUs, while AMD Radeon Pro 5300 reaches the 82nd percentile. While both are above average, NVIDIA CMP 50HX sits four percentile points higher, which corresponds to its consistent benchmark leads. The Vulkan test, while still a clear win for NVIDIA, shows a smaller margin than OpenCL, suggesting the AMD part is relatively less disadvantaged under Vulkan than under OpenCL. Still, a 32.6% deficit is not a competitive result.

Specification Differences

The two GPUs differ across nearly every core specification. NVIDIA CMP 50HX uses the TU102 chip with 18,600 million transistors on a 754 mm² die, while AMD Radeon Pro 5300 uses the Navi 14 chip with 6,400 million transistors on a 158 mm² die. Transistor density favors AMD: 40.5M per mm² versus 24.7M per mm². The process nodes differ accordingly, with AMD on 7 nm and NVIDIA on 12 nm, both from TSMC.

Memory configurations are also very different. NVIDIA CMP 50HX has 10 GB of GDDR6 on a 320-bit bus, delivering 560.0 GB/s of bandwidth. AMD Radeon Pro 5300 has 4 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s. That is a 2.5x difference in memory size and a 2.5x difference in bandwidth. Both run memory at 1750 MHz with 14 Gbps effective data rate.

Compute resources heavily favor NVIDIA. NVIDIA CMP 50HX has 3,584 shading units, 192 texture mapping units, and 80 ROPs. AMD Radeon Pro 5300 has 1,280 shading units, 80 TMUs, and 32 ROPs. NVIDIA also includes 56 ray tracing cores and 448 tensor cores, while AMD Radeon Pro 5300 has none of either. Clock speeds are closer: NVIDIA CMP 50HX runs at 1350 MHz base and 1545 MHz boost, while AMD Radeon Pro 5300 runs at 1000 MHz base and 1650 MHz boost. AMD has the higher boost clock, but NVIDIA has the higher base clock and far more execution resources.

Rates and throughput follow the same pattern. NVIDIA CMP 50HX achieves 123.6 GPixel/s pixel rate and 296.6 GTexel/s texture rate, versus AMD Radeon Pro 5300's 52.80 GPixel/s and 132.0 GTexel/s. FP32 compute is 11.07 TFLOPS for NVIDIA and 4.224 TFLOPS for AMD. FP16 is 22.15 TFLOPS for NVIDIA and 8.448 TFLOPS for AMD, both at 2:1 ratios.

Power and physical requirements differ sharply. NVIDIA CMP 50HX has a 250 W TDP, is dual-slot, requires two 8-pin power connectors, and suggests a 600 W power supply. It measures 267 mm long, 116 mm high, and 35 mm wide. AMD Radeon Pro 5300 has an 85 W TDP, is an IGP with no power connectors, and suggests a 250 W power supply. It has no recorded dimensions. The bus interfaces also differ: NVIDIA uses PCIe 1.0 x4, while AMD uses PCIe 4.0 x8.

API support shows a DirectX gap. NVIDIA CMP 50HX supports DirectX 12 Ultimate (12_2), while AMD Radeon Pro 5300 supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. Neither card has display outputs. Both are end-of-life products. NVIDIA CMP 50HX was released on 2021-06-23, while AMD Radeon Pro 5300 was released on 2020-08-03.

Architecture Differences

The two cards come from completely different architectural lineages. NVIDIA CMP 50HX is built on the Turing architecture, using the TU102 chip, and belongs to the Mining GPUs generation. AMD Radeon Pro 5300 is built on RDNA 1.0, using the Navi 14 chip, and belongs to the Radeon Pro Mac (Navi Series) generation. Turing was designed by NVIDIA as a general compute and gaming architecture with dedicated ray tracing and tensor hardware. RDNA 1.0 was AMD's first-generation RDNA design, focused on efficiency and gaming performance without dedicated ray tracing or tensor cores.

The process technology gap is significant. NVIDIA CMP 50HX is fabricated on TSMC's 12 nm node, while AMD Radeon Pro 5300 uses TSMC's 7 nm node. That explains the transistor density difference: AMD packs 40.5M transistors per mm² versus NVIDIA's 24.7M per mm². Despite the larger node, NVIDIA CMP 50HX carries 18,600 million transistors on a 754 mm² die, nearly three times AMD's 6,400 million on 158 mm². The TU102 die is one of the larger GPUs in the database, while Navi 14 is a compact mid-range chip.

Feature support diverges around ray tracing and AI acceleration. NVIDIA CMP 50HX includes 56 RT cores and 448 tensor cores, enabling hardware-accelerated ray tracing and tensor operations. AMD Radeon Pro 5300 has no RT cores and no tensor cores, meaning those workloads must run on general-purpose shading units if supported at all. This is a fundamental architectural difference, not just a spec sheet gap. NVIDIA CMP 50HX also supports DirectX 12 Ultimate, which includes features like ray tracing and variable rate shading, while AMD Radeon Pro 5300 only reaches DirectX 12 (12_1). Both cards support Vulkan 1.4 and OpenGL 4.6.

Memory architecture also differs. NVIDIA CMP 50HX uses a 320-bit memory bus with 10 GB of GDDR6, while AMD Radeon Pro 5300 uses a 128-bit bus with 4 GB. The bandwidth difference, 560.0 GB/s versus 224.0 GB/s, is a direct consequence of bus width. NVIDIA's larger memory pool and wider bus make it better suited for large datasets and memory-heavy workloads. AMD's smaller allocation reflects its intended role as a more modest, lower-power part. The bus interface also differs: NVIDIA CMP 50HX lists PCIe 1.0 x4, which appears to be an unusual limitation for a card of this compute capability, while AMD Radeon Pro 5300 uses PCIe 4.0 x8, a more modern and higher-throughput interface.

Where Each One Wins

NVIDIA CMP 50HX wins in every compute benchmark recorded in the database. OpenCL performance is 44.9% higher, and Vulkan performance is 32.6% higher. The average benchmark score is 26.7% higher, and the percentile ranking is four points higher. For OpenCL workloads, which often include general-purpose GPU compute, scientific simulation, and data processing, NVIDIA CMP 50HX is the clear choice. For Vulkan workloads, which cover modern cross-platform graphics and compute, NVIDIA CMP 50HX again dominates. Its 56 RT cores and 448 tensor cores also give it capabilities AMD Radeon Pro 5300 simply lacks. Anyone running ray-traced workloads or tensor-based operations must choose NVIDIA CMP 50HX, as AMD Radeon Pro 5300 has no hardware support for either.

AMD Radeon Pro 5300 wins where power and integration matter. It draws 85 W versus 250 W, which is less than a third of NVIDIA's power draw. It is an IGP with no power connectors, so it can fit into systems without dedicated power cabling. Its suggested power supply is 250 W versus 600 W, making it far easier to deploy in constrained builds. The 7 nm process node gives it a transistor density advantage of 40.5M per mm² versus 24.7M per mm², indicating a more modern and efficient design. For a system where thermal limits, power budgets, or physical space are the primary constraints, AMD Radeon Pro 5300 is the practical option. It also has a higher boost clock at 1650 MHz versus 1545 MHz, though this does not compensate for the massive core count disparity.

In summary, NVIDIA CMP 50HX is the performance winner across all measured benchmarks, with margins ranging from 32.6% in Vulkan to 44.9% in OpenCL. AMD Radeon Pro 5300 is the efficiency and integration winner, with far lower power requirements and a smaller physical footprint reflected in its IGP form factor. The choice depends entirely on whether the workload prioritizes raw compute throughput or system-level power efficiency. The data supports NVIDIA CMP 50HX for performance-sensitive tasks and AMD Radeon Pro 5300 for power-constrained or space-constrained deployments.
