AMD Radeon RX 5300M vs NVIDIA RTX A1000 Mobile Comparison

The Verdict

The NVIDIA RTX A1000 Mobile is the clear performance winner in this matchup. The recorded Geekbench OpenCL data shows the A1000 Mobile scoring 48,703 against the RX 5300M's 36,529, a 33.3% advantage. The A1000 Mobile also holds a higher overall percentile rank, sitting at 85 versus the RX 5300M's 80, meaning the NVIDIA part outperforms a larger share of all GPUs in the database.

For users who need maximum compute throughput in a mobile workstation, the RTX A1000 Mobile is the obvious choice. Its 60 W TDP also makes it easier to integrate into thinner, lighter chassis compared to the RX 5300M's 85 W TDP. The AMD part does have a few structural advantages, such as a 7 nm process and higher clock speeds, but the benchmark gap is simply too large to ignore.

The RX 5300M is only worth considering in legacy system configurations that require RDNA 1.0 compatibility or where the 3 GB memory pool is sufficient. Its 36,529 average score places it near the NVIDIA GeForce GTX TITAN X (36,530) and the NVIDIA T1000 (36,289), which gives a sense of its performance tier. However, the A1000 Mobile's 47,743 average score puts it in a completely different class, rivaling the AMD Radeon RX 6800 XT (48,477) in aggregate compute.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The NVIDIA RTX A1000 Mobile uses the GA107 chip built on Ampere architecture, manufactured by Samsung on an 8 nm process. The die measures 200 mm² and packs 8,700 million transistors, yielding a density of 43.5 million transistors per square millimeter. The AMD Radeon RX 5300M uses the Navi 14 chip based on RDNA 1.0, built by TSMC on a more advanced 7 nm node. Its die is smaller at 158 mm² with 6,400 million transistors, resulting in a density of 40.5 million per square millimeter.

Core configurations differ substantially. The A1000 Mobile has 2,048 shading units, 64 texture mapping units, and 32 ROPs. It also includes 16 ray tracing cores and 64 tensor cores, which enable hardware-accelerated ray tracing and AI workloads. The RX 5300M has 1,408 shading units, 88 TMUs, and 32 ROPs, but it has no ray tracing cores or tensor cores at all, which reflects its older RDNA 1.0 design.

Memory subsystems also diverge. The A1000 Mobile ships with 4 GB of GDDR6 on a 128-bit bus, delivering 176.0 GB/s of bandwidth. The RX 5300M has 3 GB of GDDR6 on a narrower 96-bit bus, providing 168.0 GB/s. Despite the smaller bus, the AMD card's faster 14 Gbps effective memory speed narrows the bandwidth gap to just 8 GB/s.

Clock behavior is another differentiator. The RX 5300M runs at a 1000 MHz base and 1445 MHz boost, with a game clock of 1181 MHz. The A1000 Mobile is more conservative, with a 630 MHz base and 1140 MHz boost. This explains why the RX 5300M achieves higher pixel and texture rates. The AMD part hits 46.24 GPixel/s and 127.2 GTexel/s, while the NVIDIA part reaches only 36.48 GPixel/s and 72.96 GTexel/s.

The A1000 Mobile also supports DirectX 12 Ultimate (12_2), while the RX 5300M is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. In FP32 compute, the A1000 Mobile leads with 4.669 TFLOPS versus 4.069 TFLOPS for the RX 5300M. However, the AMD card doubles its FP16 throughput to 8.138 TFLOPS, while the NVIDIA part stays at 4.669 TFLOPS in FP16.

Where Each One Wins

The RTX A1000 Mobile wins the only head-to-head benchmark recorded in the database, Geekbench OpenCL, by a commanding 33.3% margin. This single result, combined with its higher overall percentile (85 vs 80), indicates that the NVIDIA part is better suited for compute-heavy workloads such as data processing, rendering, and machine learning inference where tensor cores can be leveraged.

The RX 5300M does have theoretical advantages in specific rasterization metrics. Its higher pixel rate of 46.24 GPixel/s suggests it could handle fill-rate-bound scenarios more efficiently, and its 127.2 GTexel/s texture rate is significantly higher than the A1000 Mobile's 72.96 GTexel/s. These figures imply the AMD card might perform relatively better in traditional graphics workloads that rely heavily on texturing, despite losing the overall compute benchmark.

For power-constrained mobile designs, the A1000 Mobile is the more attractive option. Its 60 W TDP is 25 W lower than the RX 5300M's 85 W TDP, which allows for smaller cooling solutions and longer battery life in equivalent chassis. The A1000 Mobile is classified as an IGP (integrated graphics processor) with no power connectors, whereas the RX 5300M also lacks power connectors but carries a higher thermal envelope.

The RX 5300M's 2:1 FP16 ratio could benefit users running mixed-precision workloads that use half-precision arithmetic. Its 8.138 TFLOPS FP16 throughput is nearly double the A1000 Mobile's 4.669 TFLOPS, making it a potential choice for applications that can exploit FP16 acceleration without requiring tensor cores.

Head-to-Head Benchmarks

The database contains one direct head-to-head benchmark between these two GPUs: Geekbench OpenCL. The results are decisive. The NVIDIA RTX A1000 Mobile scored 48,703, while the AMD Radeon RX 5300M scored 36,529. This translates to a 33.3% advantage for the NVIDIA part, which is a substantial margin in mobile graphics.

Contextualizing this score, the A1000 Mobile's 48,703 result places it just 1.5% behind the AMD Radeon RX 6800 XT (48,477) in the nearest rivals list, an impressive showing for a mobile workstation GPU. It also sits comfortably above the AMD Radeon RX 6550M (46,702) by 2.2% and the Intel Arc A530M (46,614) by 2.4%. The RX 5300M, by contrast, lands in a much lower performance tier. Its 36,529 score is essentially tied with the NVIDIA GeForce GTX TITAN X (36,530) and only 0.7% ahead of the NVIDIA T1000 (36,289).

The RX 5300M's closest rival, the AMD Radeon PRO W6400, actually scores higher at 37,157, putting the RX 5300M 1.7% behind that part. Even the AMD Radeon Pro Duo (35,860) trails the RX 5300M by just 1.9%. This clustering shows that the RX 5300M sits at the upper edge of a performance band where the A1000 Mobile is not even present; the NVIDIA part operates a full tier above.

Looking at architectural explanations for the gap, the A1000 Mobile's higher shading unit count (2,048 vs 1,408) and its additional RT and tensor cores contribute to its compute advantage. The RX 5300M's higher clocks and superior fill rates do not translate into a benchmark win. The 176.0 GB/s memory bandwidth of the A1000 Mobile, despite running at a lower effective clock, edges out the RX 5300M's 168.0 GB/s.

The FP32 compute figures align with the benchmark results. The A1000 Mobile delivers 4.669 TFLOPS, which is 14.7% higher than the RX 5300M's 4.069 TFLOPS. This consistency between theoretical compute and real-world OpenCL scores reinforces the conclusion that the NVIDIA part is the stronger compute processor.

For users focused on rasterization performance, the RX 5300M's higher pixel rate (46.24 GPixel/s) and texture rate (127.2 GTexel/s) might offer some relief in specific graphics workloads. However, with no ray tracing support and a narrower 96-bit memory bus, the AMD part is fundamentally more limited in its long-term capabilities. The A1000 Mobile's support for DirectX 12 Ultimate and its tensor cores make it the more future-proof choice for professional applications that increasingly leverage these features.
