AMD Radeon RX 5300M vs NVIDIA GeForce RTX 5080 Mobile Comparison

# NVIDIA GeForce RTX 5080 Mobile vs AMD Radeon RX 5300M

The NVIDIA GeForce RTX 5080 Mobile and AMD Radeon RX 5300M occupy dramatically different positions in the mobile GPU landscape, despite their percentile rankings being surprisingly close. The RTX 5080 Mobile sits in the 81st percentile of all GPUs, while the RX 5300M ranks in the 80th percentile—yet the actual benchmark data tells a story of overwhelming generational and architectural superiority. The RTX 5080 Mobile averages 38,349 across all benchmark tests, compared to 36,529 for the RX 5300M, a difference that appears modest at first glance but becomes stark when examining individual workloads. The RX 5300M, released in November 2019, is now end-of-life, while the RTX 5080 Mobile launched in April 2025 as an active product, representing a five-year gap in mobile GPU evolution.

Where Each One Wins

The benchmark data is unambiguous: the NVIDIA GeForce RTX 5080 Mobile wins the only head-to-head benchmark available, and it does so by an extraordinary margin. In the Geekbench OpenCL test, the RTX 5080 Mobile scores 166,986 compared to the RX 5300M's 36,529, a delta of 357.1%. This is not a close contest by any measure—it is a complete sweep. The wins tally shows 1 win for NVIDIA and 0 for AMD, reflecting the complete absence of any benchmark category where the RX 5300M emerges ahead.

Looking at the broader benchmark suite for the RTX 5080 Mobile, it demonstrates strength across multiple API generations. Its PassMark G3D score of 27,711 indicates strong DirectX performance across older and newer workloads, while the Geekbench Vulkan score of 169,754 shows particular proficiency in modern graphics APIs. The RX 5300M, by contrast, has only a single benchmark result in the data—the Geekbench OpenCL score of 36,529—which limits direct comparison but also highlights its narrower testing footprint. The RTX 5080 Mobile's PassMark GPU Compute score of 12,134 further reinforces its compute-oriented strengths, a category where the RX 5300M has no recorded data to contest the comparison.

The use-case implications are clear: the RTX 5080 Mobile is designed for demanding modern workloads including ray tracing, compute-heavy tasks, and high-resolution gaming, while the RX 5300M belongs to an earlier era of mobile graphics focused on more modest performance targets. The 80th percentile ranking for the RX 5300M is somewhat misleading in this context, as it reflects performance relative to all GPUs including desktop parts, but the absolute performance gap between these two mobile offerings is vast.

Architecture Differences

The architectural divide between these two GPUs is generational and fundamental. The RTX 5080 Mobile uses the GB203 chip built on NVIDIA's Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC with 45,600 million transistors on a 378 mm² die. The RX 5300M uses the Navi 14 chip with AMD's RDNA 1.0 architecture, built on a 7 nm process at TSMC with just 6,400 million transistors on a 158 mm² die. This represents a 7.1x difference in transistor count and a 2.4x difference in die size, with the RTX 5080 Mobile achieving a transistor density of 120.6 million transistors per mm² compared to 40.5 million per mm² for the RX 5300M.

Memory configurations differ equally dramatically. The RTX 5080 Mobile features 16 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The RX 5300M has 3 GB of GDDR6 on a 96-bit bus, providing 168.0 GB/s. That is a 5.3x bandwidth advantage for the NVIDIA part, alongside over 5x the memory capacity—critical for modern game textures, AI workloads, and high-resolution rendering. The RTX 5080 Mobile also introduces dedicated hardware the RX 5300M lacks entirely: 60 ray tracing cores and 240 tensor cores, enabling hardware-accelerated ray tracing and AI features that are absent from the RDNA 1.0 architecture.

Compute resources show similar disparity. The RTX 5080 Mobile packs 7,680 shading units, 240 TMUs, and 96 ROPs, compared to 1,408 shading units, 88 TMUs, and 32 ROPs on the RX 5300M. The FP32 throughput of 23.04 TFLOPS on the RTX 5080 Mobile is 5.7x higher than the RX 5300M's 4.069 TFLOPS. Interestingly, the RX 5300M has a 2:1 FP16 ratio delivering 8.138 TFLOPS, while the RTX 5080 Mobile offers 1:1 FP16 at 23.04 TFLOPS—meaning NVIDIA's card matches its FP32 rate for half-precision work, a notable advantage for AI inference.

Head-to-Head Benchmarks

The sole head-to-head benchmark is Geekbench OpenCL, and the results are staggering. The RTX 5080 Mobile scores 166,986 against the RX 5300M's 36,529, producing a delta of 357.1%. This means the NVIDIA GPU delivers roughly 4.6x the OpenCL compute performance of the AMD part, a margin that dwarfs even the transistor count difference. OpenCL performance is particularly relevant for general-purpose GPU computing, scientific workloads, and cross-platform applications, making this a meaningful real-world advantage rather than a synthetic anomaly.

Contextualizing through the nearest rivals provides additional perspective. The RTX 5080 Mobile's average score of 38,349 places it 0.1% ahead of the NVIDIA GeForce MX570 (38,299) and 0.6% ahead of the RTX 4080 Mobile (38,135), but 0.9% behind the MX570 A (38,691) and the AMD Radeon Pro 580X (38,706). This clustering suggests the RTX 5080 Mobile's average benchmark score is competitive with a range of mid-to-high-end mobile and desktop GPUs, though its individual Geekbench OpenCL result stands far above these averages.

The RX 5300M's average score of 36,529 places it essentially tied with the NVIDIA GeForce GTX TITAN X (36,530, 0% delta), 0.7% ahead of the NVIDIA T1000 (36,289), 1.7% behind the AMD Radeon PRO W6400 (37,157), and 1.9% ahead of the AMD Radeon Pro Duo (35,860). This positioning reveals that while the RX 5300M's average is in a similar percentile band to the RTX 5080 Mobile, its performance ceiling is fundamentally lower, and its single benchmark result means the average is derived from just one data point.

The Verdict

The data leaves no room for ambiguity: the NVIDIA GeForce RTX 5080 Mobile is the superior GPU in every measurable way. It wins the only head-to-head benchmark by 357.1%, offers 5.3x more memory bandwidth, 7.1x more transistors, and includes hardware features like ray tracing and tensor cores that the RX 5300M simply does not have. The RTX 5080 Mobile's 81st percentile ranking versus the RX 5300M's 80th percentile actually understates the performance gap, as the percentile ranks reflect relative position across all GPUs rather than direct comparison between these two parts.

For users seeking a modern mobile GPU capable of handling contemporary gaming, compute, and AI workloads, the RTX 5080 Mobile is the clear choice based on this data. Its 16 GB of GDDR7 memory, 23.04 TFLOPS of FP32 performance, and Blackwell 2.0 architecture position it as a future-proof option. The RX 5300M, with its 3 GB GDDR6 memory, 4.069 TFLOPS FP32, and RDNA 1.0 architecture, belongs to an earlier era of mobile graphics and is now end-of-life. While the RX 5300M's 80th percentile ranking suggests it was competitive in its time, the five-year gap between their release dates is evident in every specification and benchmark result. The verdict is straightforward: for any workload measured in the data, the RTX 5080 Mobile is the definitive winner.
