AMD Radeon RX 5300M vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

AMD Radeon RX 5300M and NVIDIA GeForce RTX 5070 Ti Mobile sit at opposite ends of the mobile GPU spectrum. The RX 5300M is an end-of-life entry-level part from 2019, while the RTX 5070 Ti Mobile is an active, high-end Blackwell part from 2025. The benchmark data shows a massive generational gulf: in the sole shared Geekbench OpenCL test, the RTX 5070 Ti Mobile scores 143870 against the RX 5300M's 36529, a 74.6% difference in favor of NVIDIA. This comparison is less about close competition and more about quantifying how far mobile graphics have come.

FAQ

Q: Do both GPUs support modern graphics APIs?

A: Both support DirectX 12, OpenGL 4.6, and Vulkan 1.4. However, the RTX 5070 Ti Mobile supports DirectX 12 Ultimate (12_2), while the RX 5300M supports only DirectX 12 (12_1). The RTX 5070 Ti Mobile also includes dedicated ray tracing and tensor cores, which the RX 5300M lacks entirely.

Q: What are the memory configuration differences?

A: The RX 5300M has 3 GB of GDDR6 on a 96-bit bus, delivering 168.0 GB/s bandwidth. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s bandwidth. That is four times the capacity and exactly four times the bandwidth.

Q: How do their power requirements compare?

A: The RX 5300M has a TDP of 85 W, while the RTX 5070 Ti Mobile has a TDP of 60 W. Despite having a much higher transistor count and performance, the RTX 5070 Ti Mobile is rated for lower power draw. Neither card uses external power connectors.

Q: What is the transistor density difference?

A: The RX 5300M packs 6,400 million transistors on a 158 mm² die, yielding 40.5M transistors per mm². The RTX 5070 Ti Mobile packs 31,100 million transistors on a 263 mm² die, yielding 118.3M transistors per mm². That is a 77.6M per mm² density advantage for the NVIDIA part.

Architecture Differences

The architectural gap is fundamental. The RX 5300M is built on RDNA 1.0, AMD's first-generation Navi architecture, using a 7 nm TSMC process. It contains 1,408 shading units, 88 texture mapping units, and 32 ROPs, with no ray tracing or tensor cores. Its compute throughput is rated at 4.069 TFLOPS for FP32 and 8.138 TFLOPS for FP16, the latter at a 2:1 ratio. The chip integrates 6,400 million transistors on a 158 mm² die.

The RTX 5070 Ti Mobile uses Blackwell 2.0 on a 5 nm TSMC process, a considerably denser design. It features 5,888 shading units, 184 TMUs, and 80 ROPs, plus 46 ray tracing cores and 184 tensor cores. Its FP32 and FP16 performance are both rated at 17.04 TFLOPS, with a 1:1 ratio. The GB205 chip contains 31,100 million transistors on a 263 mm² die, making it roughly 4.9 times larger in transistor count and 1.7 times larger in die area than the Navi 14.

The memory subsystems are equally divergent. The RX 5300M uses 3 GB of GDDR6 with a 96-bit bus and 168.0 GB/s bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 with a 192-bit bus and 672.0 GB/s bandwidth. The NVIDIA part also has a much faster pixel rate (115.8 GPixel/s vs 46.24 GPixel/s) and texture rate (266.2 GTexel/s vs 127.2 GTexel/s).

Process node differences are stark: 7 nm for AMD versus 5 nm for NVIDIA. The RTX 5070 Ti Mobile's transistor density of 118.3M per mm² is nearly triple the RX 5300M's 40.5M per mm². The bus interface also differs, with the RX 5300M using PCIe 4.0 x8 and the RTX 5070 Ti Mobile using PCIe 5.0 x16.

Head-to-Head Benchmarks

There is exactly one direct benchmark comparison: Geekbench OpenCL. The RX 5300M scores 36529, while the RTX 5070 Ti Mobile scores 143870. The delta is -74.6% from NVIDIA's perspective, meaning the RTX 5070 Ti Mobile is roughly 3.9 times faster in raw compute throughput. This aligns with the theoretical FP32 figures: 17.04 TFLOPS versus 4.069 TFLOPS, a 4.2x difference.

The RTX 5070 Ti Mobile also has additional benchmark results that the RX 5300M lacks entirely. In Vulkan, it scores 139213. In Passmark tests, it scores 24004 in G3D, 10101 in GPU compute, 981 in G2D, and 259 in DirectX 9. These extra data points show a well-rounded part, but no direct comparison is possible because the RX 5300M has no corresponding scores.

For context, the RX 5300M's nearest rivals in the database are the NVIDIA GeForce GTX TITAN X (36530, 0% delta), NVIDIA T1000 (36289, 0.7% delta), AMD Radeon PRO W6400 (37157, -1.7% delta), and AMD Radeon Pro Duo (35860, 1.9% delta). The RTX 5070 Ti Mobile's nearest rivals are the NVIDIA Quadro GV100 (35520, -0.2% delta), AMD Radeon Pro Duo (35860, -1.2% delta), NVIDIA A2 (34690, 2.1% delta), and NVIDIA T1000 (36289, -2.4% delta). Interestingly, both GPUs share the AMD Radeon Pro Duo and NVIDIA T1000 as nearby rivals, but at very different absolute score levels.

Specification Differences

The two GPUs differ in nearly every measurable specification. The RX 5300M has a base clock of 1000 MHz and a boost clock of 1445 MHz, with a game clock of 1181 MHz. The RTX 5070 Ti Mobile has a lower base clock of 847 MHz but a slightly higher boost clock of 1447 MHz, with no game clock listed. Memory clocks are the same at 1750 MHz, but the effective data rate differs: 14 Gbps for AMD versus 28 Gbps for NVIDIA.

Generation: Navi Mobile (RX 5000M) versus GeForce 50 Mobile. Predecessor: Polaris Mobile versus GeForce 40 Mobile.

The Verdict

The data is unambiguous: the RTX 5070 Ti Mobile outperforms the RX 5300M by a massive margin in every comparable metric. The sole head-to-head benchmark shows a 74.6% advantage for NVIDIA. The RTX 5070 Ti Mobile has four times the memory capacity, four times the bandwidth, roughly 4.2 times the shading units, and over four times the FP32 throughput. It also adds ray tracing and tensor cores that the RX 5300M does not have at all.

The RX 5300M is an end-of-life product from 2019, with no active production status. Its only advantage is a lower transistor count and smaller die, which are irrelevant to performance. Its TDP is higher (85 W versus 60 W), meaning it consumes more power while delivering far less performance. The RTX 5070 Ti Mobile is the clear choice for any modern workload, from gaming to compute tasks.

However, the RTX 5070 Ti Mobile is not without context. Its average benchmark score of 35435 is lower than its Geekbench OpenCL score of 143870, because the average includes many lower-scoring DirectX and Passmark tests. Its percentile vs all GPUs is 80, identical to the RX 5300M's percentile. This suggests that while the RTX 5070 Ti Mobile is a high-end part, the RX 5300M also sits at the 80th percentile, likely due to the age of the database population.

Where Each One Wins

The RTX 5070 Ti Mobile wins in compute performance, memory capacity, memory bandwidth, feature set, and efficiency. It has ray tracing cores, tensor cores, DirectX 12 Ultimate support, and a PCIe 5.0 x16 interface. It is also more power-efficient per unit of performance, given its lower TDP of 60 W versus 85 W. Any workload that benefits from FP32 or FP16 compute, large textures, or high-bandwidth memory will favor the NVIDIA part.

The RX 5300M has no benchmark wins. In the single head-to-head test, it loses by 74.6%. It has no ray tracing, no tensor cores, less memory, lower bandwidth, and fewer shading units. Its only potential advantage is its smaller die size and lower transistor count, which could theoretically translate to lower manufacturing costs, but no pricing data is available and this is not a performance benefit.

For a builder choosing between these two, the decision is clear. The RTX 5070 Ti Mobile is the superior GPU in every measured category. The RX 5300M is a legacy part that cannot compete in any scenario where performance matters. The only reason to select the RX 5300M would be if it were the only compatible option for an older system, but the data shows no scenario where it wins.
