AMD Radeon Pro 580 vs AMD Radeon RX 5300M Comparison

The AMD Radeon Pro 580 and AMD Radeon RX 5300M are two very different mobile graphics solutions from different eras, and the data shows a clear, if narrow, winner in compute performance. The Radeon Pro 580, built on a mature 14 nm GCN architecture, holds a 5.3% lead in the single shared benchmark, while the RX 5300M counters with a far more modern feature set and significantly higher clock speeds. The choice between them is not about raw speed alone, but about which generation’s compromises fit the intended workload.

Where Each One Wins

The Radeon Pro 580 is the outright winner in raw compute throughput. In the only direct head-to-head benchmark available, Geekbench OpenCL, it scores 38,457 against the RX 5300M’s 36,529, a 5.3% advantage. This lead is rooted in its hardware design: it packs 2,304 shading units, 144 texture mapping units, and 32 ROPs, all running at a boost clock of 1200 MHz. This configuration yields 5.530 TFLOPS of FP32 performance and a texture rate of 172.8 GTexel/s, figures that simply outpace the newer chip. For compute-heavy tasks like rendering or scientific calculations that leverage OpenCL, the Pro 580 is the stronger candidate.

The Radeon RX 5300M, however, wins on architectural efficiency and generational features. Its RDNA 1.0 architecture, fabricated on a 7 nm TSMC process, is a significant leap over the Pro 580’s 14 nm GlobalFoundries node. While it has fewer cores (1,408 shading units) and lower FP32 throughput (4.069 TFLOPS), it operates at a much higher boost clock of 1445 MHz and a game clock of 1181 MHz. It also doubles the FP16 performance to 8.138 TFLOPS (2:1), a capability the Pro 580 lacks, as it runs FP16 at a 1:1 ratio with FP32 (5.530 TFLOPS). This makes the RX 5300M more adaptable for workloads that can leverage mixed-precision math.

Architecture Differences

The fundamental split is between GCN 4.0 and RDNA 1.0. The Pro 580 uses the Ellesmere chip, a 14 nm design with 5,700 million transistors on a 232 mm² die, resulting in a transistor density of 24.6M per mm². The RX 5300M uses the Navi 14 chip, a 7 nm design with 6,400 million transistors on a much smaller 158 mm² die, achieving a density of 40.5M per mm². This density difference explains the RX 5300M’s superior power efficiency, as reflected in its 85 W TDP versus the Pro 580’s 185 W TDP.

Memory configurations also diverge sharply. The Pro 580 features 8 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s of bandwidth. The RX 5300M uses 3 GB of GDDR6 on a narrower 96-bit bus, yielding 168.0 GB/s. While the Pro 580 has more capacity and bandwidth, the RX 5300M’s GDDR6 memory runs at a higher effective speed of 14 Gbps versus 6.8 Gbps. The Pro 580 also supports PCIe 3.0 x16, while the RX 5300M uses PCIe 4.0 x8, which offers similar bandwidth on a newer standard. In terms of API support, the RX 5300M is ahead with DirectX 12_1 and Vulkan 1.4, whereas the Pro 580 caps at DirectX 12_0 and Vulkan 1.3.

Head-to-Head Benchmarks

The single data point for direct comparison is the Geekbench OpenCL test. Here, the Pro 580 scores 38,457, while the RX 5300M scores 36,529. The delta is 5.3% in favor of the Pro 580. This result is consistent with the Pro 580’s higher FP32 compute rating (5.530 TFLOPS) and wider memory bus. The RX 5300M’s lower score, despite its higher boost clock, reflects its reduced core count and narrower memory interface.

Looking at broader benchmark context, the Pro 580 also has additional scores in Geekbench Metal (39,213) and Geekbench Vulkan (43,285), which the RX 5300M lacks. Its average benchmark score across all tests is 40,318, placing it in the 82nd percentile of all GPUs. The RX 5300M’s average score is 36,529, placing it in the 80th percentile. The Pro 580’s nearest rival, the NVIDIA GeForce RTX 5070, scores 40,377, a mere 0.1% difference, showing the Pro 580 is competitive with much newer high-end parts in compute tasks.

FAQ

Q: Which card has higher raw compute performance?

A: The AMD Radeon Pro 580. It delivers 5.530 TFLOPS of FP32 performance and scores 5.3% higher than the RX 5300M in the Geekbench OpenCL test (38,457 vs 36,529).

Q: Does the RX 5300M have any performance advantage?

A: Yes, in FP16 compute. The RX 5300M outputs 8.138 TFLOPS (2:1 ratio), while the Pro 580 is limited to 5.530 TFLOPS (1:1 ratio). This makes the RX 5300M better suited for workloads using mixed-precision arithmetic.

Q: Which card has more memory and bandwidth?

A: The AMD Radeon Pro 580. It has 8 GB of GDDR5 on a 256-bit bus with 217.0 GB/s bandwidth. The RX 5300M has 3 GB of GDDR6 on a 96-bit bus with 168.0 GB/s bandwidth.

Q: How do their power requirements compare?

A: The RX 5300M is far more efficient with an 85 W TDP, while the Pro 580 draws 185 W. Neither card requires external power connectors, and both use portable device dependent display outputs.

Q: Which card supports newer graphics APIs?

A: The Radeon RX 5300M. It supports DirectX 12_1 and Vulkan 1.4, whereas the Radeon Pro 580 supports DirectX 12_0 and Vulkan 1.3. Both support OpenGL 4.6.

Q: How do their overall performance percentiles compare?

A: The Pro 580 sits in the 82nd percentile of all GPUs with an average score of 40,318. The RX 5300M sits in the 80th percentile with an average score of 36,529.

The Verdict

The data supports a clear verdict: pick the AMD Radeon Pro 580 for maximum compute throughput. Its 5.3% lead in OpenCL, higher FP32 TFLOPS, and larger memory pool make it the superior choice for compute-oriented tasks. Its 82nd percentile ranking and proximity to the NVIDIA GeForce RTX 5070 (0.1% difference) underscore its lasting compute strength.

Pick the AMD Radeon RX 5300M for efficiency and modern features. Its 7 nm RDNA 1.0 architecture delivers a 100 W lower TDP (85 W vs 185 W), support for DirectX 12_1 and Vulkan 1.4, and double-rate FP16 performance. These traits make it a better fit for portable devices where battery life and thermal headroom matter, and for workloads that can exploit mixed-precision or newer API features. Its 80th percentile ranking is respectable, but it cannot match the Pro 580’s raw throughput.
