AMD Instinct MI325X vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The database does not record any direct head-to-head benchmark comparisons between the AMD Instinct MI325X and the NVIDIA GeForce RTX 5070 Mobile. The MI325X has no benchmark entries, no average score, and no nearest rivals listed. Its percentile rank against all GPUs is 50, which places it at the median of the recorded database population, but this is a positional marker rather than a measured performance result.

The RTX 5070 Mobile, by contrast, has a full suite of recorded measurements. Its average benchmark score is 29928, and it sits at the 75th percentile against all GPUs. The nearest rivals in the database are the NVIDIA GeForce RTX 3070 Ti (average score 29945, delta of -0.1%), the NVIDIA GeForce RTX 2080 Ti (average score 29783, delta of +0.5%), the AMD Radeon RX 6800 (average score 30095, delta of -0.6%), and the AMD Radeon RX 6700 (average score 30433, delta of -1.7%). These deltas are all within 1.7% of the RTX 5070 Mobile's average, indicating that the mobile part lands in a tightly clustered performance band around these desktop and older mobile cards. The RTX 5070 Mobile is effectively 0.1% behind the RTX 3070 Ti, 0.5% ahead of the RTX 2080 Ti, 0.6% behind the RX 6800, and 1.7% behind the RX 6700.

Individual workload scores for the RTX 5070 Mobile show notable variation. In Geekbench OpenCL it records 122238, and in Geekbench Vulkan it records 116960. Passmark tests tell a different story: DirectX 10 scores 129, DirectX 11 scores 192, DirectX 12 scores 93, DirectX 9 scores 214, G2D scores 896, G3D scores 20355, and GPU compute scores 8279. The G3D score of 20355 dominates the average, while the compute score of 8279 is substantial but lower. The DirectX legacy tests are all below 215, which suggests these older API paths are not the card's strength. The gap between G3D (20355) and GPU compute (8279) indicates that rasterization-style workloads score more than twice as high as compute workloads in Passmark's methodology.

Since the MI325X has no recorded scores, the head-to-head comparison is asymmetric. The data permits only a directional statement: the RTX 5070 Mobile has measurable performance across nine tests, while the MI325X has none. The MI325X's 50th percentile rank is a placeholder, not a result. This means any direct numeric comparison between the two parts is impossible from the database. The analysis must instead rely on architectural and specification differences, which are substantial.

Architecture Differences

The MI325X is built on CDNA 3.0 architecture, specifically designed for compute accelerators. Its chip is codenamed Aqua Vanjaram, and it belongs to the Instinct (MIx) generation. The RTX 5070 Mobile uses Blackwell 2.0 architecture, part of the GeForce 50-series, with the GB206 chip. These are fundamentally different design philosophies: CDNA 3.0 targets data center compute without display outputs, while Blackwell 2.0 targets client graphics and portable devices.

The transistor counts diverge sharply. The MI325X contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The RTX 5070 Mobile contains 21,900 million transistors on a 181 mm² die, with a density of 121.0 million per square millimeter. The MI325X has about seven times more transistors and a die that is over five times larger. Both use a 5 nm process from TSMC, so the density difference comes from design choices rather than process node.

The MI325X has 19456 shading units and 1216 texture mapping units, but zero ROPs and zero pixel rate. This reflects its compute-only nature. The RTX 5070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. It also has a pixel rate of 68.40 GPixel/s and a texture rate of 205.2 GTexel/s. The MI325X has a texture rate of 2,553.6 GTexel/s, which is over 12 times higher than the RTX 5070 Mobile, but it has no rasterization pipeline at all.

The memory subsystems are architecturally distinct. The MI325X uses HBM3e with a massive 8192-bit bus, while the RTX 5070 Mobile uses GDDR7 with a 128-bit bus. The MI325X's memory clock is listed as 1500 MHz with 6 Gbps effective, and the RTX 5070 Mobile's memory clock is also 1500 MHz but with 24 Gbps effective. Despite the higher effective GDDR7 speed, the MI325X's enormous bus width gives it 6.14 TB/s bandwidth versus 384.0 GB/s.

The MI325X has no display outputs, no API support, and no power connectors, using an OAM Module slot width. The RTX 5070 Mobile is an IGP with display outputs described as "Portable Device Dependent." The MI325X's APIs are all N/A, confirming it is not a graphics card in the consumer sense. The RTX 5070 Mobile supports full modern graphics APIs.

Specification Differences

The two parts differ in nearly every specification field. The MI325X has a base clock of 1000 MHz and a boost clock of 2100 MHz, while the RTX 5070 Mobile has a base clock of 907 MHz and a boost of 1425 MHz. The MI325X boosts about 675 MHz higher.

Release dates differ: the MI325X launched on 2024-10-09, and the RTX 5070 Mobile launched on 2025-04-14. The MI325X's predecessor is Radeon Instinct, while the RTX 5070 Mobile's predecessor is GeForce 40 Mobile. The RTX 5070 Mobile has an active production status; the MI325X has none listed. Neither part has a launch MSRP in the database.

The Verdict

The data points to two different products for two different workloads. The MI325X is a compute accelerator with no graphics capabilities, no display outputs, and no API support. Its 81.72 TFLOPS FP32, 256 GB HBM3e, and 6.14 TB/s bandwidth position it as a data center part for memory-bound and throughput-bound compute tasks. Its 1000 W TDP and 1400 W suggested PSU confirm it requires server infrastructure.

The RTX 5070 Mobile is a client graphics processor. Its 13.13 TFLOPS FP32, 8 GB GDDR7, and 384.0 GB/s bandwidth are far lower, but it supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, and it has ray tracing and tensor cores. Its 50 W TDP fits portable devices. The benchmark data shows it performs within 1.7% of the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700 in average score, with the RTX 5070 Mobile landing slightly ahead of the RTX 2080 Ti and slightly behind the other three.

The MI325X has no recorded benchmark scores, so the database cannot confirm its real-world performance. Its 50th percentile rank is a default value, not a measured outcome. In contrast, the RTX 5070 Mobile's 75th percentile rank is backed by nine separate test scores. The verdict is therefore not about which part is "better" in absolute terms, but which part fits which role. The MI325X is for compute acceleration without graphics output; the RTX 5070 Mobile is for graphics and compute in a portable form factor.

Where Each One Wins

The MI325X wins decisively in raw compute throughput. Its FP32 of 81.72 TFLOPS is over six times the RTX 5070 Mobile's 13.13 TFLOPS. Its texture rate of 2,553.6 GTexel/s is over twelve times higher. Its memory bandwidth of 6.14 TB/s is roughly sixteen times higher, and its capacity of 256 GB is thirty-two times larger. These advantages point to workloads like large-scale matrix operations, high-bandwidth data movement, and memory-resident datasets.

The RTX 5070 Mobile wins in every graphics-specific category. It has 48 ROPs versus zero, a pixel rate of 68.40 GPixel/s versus zero, 36 ray tracing cores versus none, and 144 tensor cores versus none. It supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, while the MI325X has N/A for all. It has display outputs, while the MI325X has none. Its TDP of 50 W versus 1000 W makes it viable for portable devices, and its production status is Active.

In benchmark terms, only the RTX 5070 Mobile has scores. Its G3D score of 20355 indicates strong rasterization performance, while its GPU compute score of 8279 is lower but still substantial. The Geekbench OpenCL score of 122238 and Vulkan score of 116960 show cross-API compute capability. The MI325X has no measured scores to claim any benchmark win.

The practical split is clear: the MI325X wins where memory capacity and raw throughput are paramount, and the RTX 5070 Mobile wins where graphics APIs, ray tracing, and low power consumption matter. The MI325X has no pixel rate, no ROPs, and no display outputs, so it cannot render graphics at all. The RTX 5070 Mobile has graphics output and API support, so it can handle both rasterization and compute, albeit at far lower throughput and bandwidth than the MI325X.
