AMD Radeon RX 5300M vs NVIDIA RTX A5000 Comparison

AMD Radeon RX 5300M and NVIDIA RTX A5000 sit on opposite ends of the mobile and workstation GPU spectrum, yet the benchmark data reveals a surprisingly narrow gap in their average scores despite a monumental difference in raw specifications. The RX 5300M, a 2019-era entry-level mobile part, posts an average benchmark score of 36,529, while the RTX A5000, a 2021 professional workstation behemoth, averages 33,622. This counterintuitive result stems from the fact that the A5000’s average is dragged down by a suite of diverse tests—including older DirectX 9 and 10 workloads—where its architecture does not dominate, while the RX 5300M’s single OpenCL score is consistently high. The head-to-head comparison, however, tells a far more decisive story when isolating compute performance.

Head-to-Head Benchmarks

The only directly comparable benchmark between the two GPUs is Geekbench OpenCL, and the results are lopsided. The NVIDIA RTX A5000 scores 157,905, while the AMD Radeon RX 5300M manages 36,529. This translates to a delta of -76.9% for the AMD part, meaning the RTX A5000 is over four times faster in this compute-oriented test. The magnitude of this gap is staggering, especially considering that the RX 5300M’s score places it in the 80th percentile of all GPUs, while the RTX A5000 sits slightly lower at the 78th percentile. This discrepancy highlights a critical nuance: percentile rankings based on aggregate scores can obscure massive single-test disparities.

Breaking down the RTX A5000’s individual benchmark results provides context for its lower aggregate percentile. In Passmark G3D, it scores 22,541, which is a strong result but not extraordinary. Its Passmark GPU Compute score of 12,455 is respectable, yet its DirectX 12 Passmark score is a mere 87, and DirectX 10 scores just 153. These legacy API tests appear to penalize the Ampere architecture disproportionately, pulling the average down. In contrast, the RX 5300M’s single Geekbench OpenCL result of 36,529 is its only data point, giving it a clean, unweighted average that benefits from the absence of weaker legacy test scores.

When examining the nearest rivals for each card, the data reveals interesting positioning. The RX 5300M’s closest competitor is the NVIDIA GeForce GTX TITAN X, with a score of 36,530 and a delta of 0%—essentially a statistical tie. It also edges out the NVIDIA T1000 by 0.7% and the AMD Radeon Pro Duo by 1.9%, while trailing the AMD Radeon PRO W6400 by 1.7%. The RTX A5000, meanwhile, sits within 1% of the NVIDIA GeForce GTX 1060 5 GB, AMD Radeon RX 7700S, AMD Radeon HD 7950, and AMD Radeon RX 480 in aggregate scoring, with deltas ranging from -0.2% to -1.1%. This clustering of such disparate hardware—from a 2012 HD 7950 to a modern RX 7700S—around the A5000’s average underscores how misleading aggregate scores can be for professional workstation GPUs.

Architecture Differences

The architectural divide between these two GPUs is generational and fundamental. The AMD Radeon RX 5300M uses the Navi 14 chip built on RDNA 1.0 architecture, manufactured on a 7 nm process at TSMC. This chip contains 6,400 million transistors on a 158 mm² die, yielding a transistor density of 40.5 million per mm². The NVIDIA RTX A5000, by contrast, employs the GA102 chip with Ampere architecture, fabricated on Samsung’s 8 nm process. It packs 28,300 million transistors onto a 628 mm² die, with a density of 45.1 million per mm². The RTX A5000’s die is nearly four times larger and holds over four times the transistors, reflecting its workstation-class positioning.

The memory subsystems diverge sharply. The RX 5300M features 3 GB of GDDR6 on a 96-bit bus, delivering 168.0 GB/s of bandwidth. The RTX A5000 offers 24 GB of GDDR6 on a 384-bit bus, achieving 768.0 GB/s—a 4.6-fold increase in capacity and a similar jump in bandwidth. Clock speeds also favor the NVIDIA part: the RTX A5000 runs at 1170 MHz base and 1695 MHz boost, while the RX 5300M operates at 1000 MHz base, 1181 MHz game, and 1445 MHz boost.

Compute resources reveal the true scale of difference. The RX 5300M has 1,408 shading units, 88 texture mapping units, and 32 ROPs, producing 4.069 TFLOPS FP32 and 8.138 TFLOPS FP16 (2:1 ratio). The RTX A5000 possesses 8,192 shading units, 256 TMUs, and 96 ROPs, achieving 27.77 TFLOPS for both FP32 and FP16 (1:1 ratio). Critically, the RTX A5000 includes 64 RT cores and 256 tensor cores, features entirely absent from the RX 5300M. The NVIDIA card also supports DirectX 12 Ultimate (12_2), while the AMD part is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The Verdict

The data points to a clear conclusion: the RTX A5000 is the superior performer for compute-heavy applications, delivering a 76.9% higher OpenCL score than the RX 5300M. Its 24 GB memory capacity, 384-bit bus, and 27.77 TFLOPS FP32 throughput position it as a professional workstation tool, while the RX 5300M’s 3 GB frame buffer and 4.069 TFLOPS make it a modest entry-level mobile solution. However, the aggregate benchmark scores—36,529 for AMD versus 33,622 for NVIDIA—suggest that in real-world mixed workloads, the RX 5300M holds its own relative to its much larger counterpart. This is likely because the RTX A5000’s legacy DirectX scores drag its average down, whereas the RX 5300M benefits from having only one favorable benchmark in its dataset.

For users prioritizing raw compute throughput, memory capacity, and modern feature support like ray tracing and tensor operations, the RTX A5000 is the only choice. For those constrained to a low-power mobile form factor (85 W TDP versus 230 W) and needing basic 3D acceleration, the RX 5300M offers a surprisingly competitive aggregate performance profile. The RTX A5000’s PCIe 4.0 x16 interface and dual-slot design also indicate a desktop workstation card, while the RX 5300M’s portable-device-dependent outputs and PCIe 4.0 x8 bus confirm its laptop orientation.

Specification Differences

The two GPUs differ across nearly every measurable specification. The RX 5300M uses a 7 nm TSMC process with 6,400 million transistors on a 158 mm² die, while the RTX A5000 uses an 8 nm Samsung process with 28,300 million transistors on a 628 mm² die. The memory configuration is starkly different: 3 GB GDDR6 on a 96-bit bus (168.0 GB/s) versus 24 GB GDDR6 on a 384-bit bus (768.0 GB/s). Clock speeds show the NVIDIA card running higher at 1170 MHz base and 1695 MHz boost, compared to 1000 MHz base, 1181 MHz game, and 1445 MHz boost for AMD.

Core counts are massively skewed: 1,408 shading units, 88 TMUs, and 32 ROPs for the RX 5300M versus 8,192 shading units, 256 TMUs, and 96 ROPs for the RTX A5000. The RTX A5000 uniquely features 64 RT cores and 256 tensor cores. Compute throughput is 4.069 TFLOPS FP32 and 8.138 FP16 for AMD, while NVIDIA achieves 27.77 TFLOPS for both FP32 and FP16. Power consumption is 85 W versus 230 W, with the RTX A5000 requiring a single 8-pin power connector and a 550 W suggested PSU. The NVIDIA card is dual-slot, 267 mm long, and 112 mm tall, with 4x DisplayPort 1.4a outputs; the RX 5300M has no specified dimensions or outputs beyond being portable-device dependent. The RTX A5000 supports DirectX 12 Ultimate, while the RX 5300M is limited to DirectX 12 (12_1). Release dates are November 12, 2019, for AMD and April 11, 2021, for NVIDIA.

Where Each One Wins

The RTX A5000 wins decisively in compute performance, as evidenced by its 157,905 OpenCL score—a 76.9% advantage over the RX 5300M. It also dominates in memory capacity (24 GB versus 3 GB), memory bandwidth (768.0 GB/s versus 168.0 GB/s), and raw throughput metrics like pixel rate (162.7 GPixel/s versus 46.24 GPixel/s) and texture rate (433.9 GTexel/s versus 127.2 GTexel/s). The presence of RT cores and tensor cores gives it a unique advantage for ray-traced workloads and AI inference tasks, which the RX 5300M cannot perform at all. Its higher base and boost clocks, larger bus interface (x16 versus x8), and support for DirectX 12 Ultimate further cement its position for professional 3D rendering and scientific computing.

The RX 5300M wins in efficiency and portability. Its 85 W TDP is less than a third of the RTX A5000’s 230 W, making it suitable for thin-and-light laptops without external power connectors. Its smaller die (158 mm² versus 628 mm²) and lower transistor count imply lower manufacturing cost and heat output. In aggregate benchmark terms, the RX 5300M actually scores higher (36,529 versus 33,622) and ranks higher in percentile (80th versus 78th), suggesting that for general-purpose 3D acceleration and legacy DirectX workloads, it may offer a more balanced performance profile per watt. The AMD card’s 8.138 TFLOPS FP16 throughput, double its FP32 rate, also indicates strong half-precision compute for its class. Ultimately, the RX 5300M is the pragmatic choice for mobile users needing basic GPU acceleration, while the RTX A5000 is the undisputed champion for heavy compute, large datasets, and workstation-grade rendering tasks.
