AMD Instinct MI300A vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Instinct MI300A and the NVIDIA GeForce RTX 5070 Ti Mobile. The head-to-head benchmark field is empty, and neither product has a wins tally in the database. This absence of comparative testing data means any analysis of relative performance must rely on the individual specification sheets and the benchmark scores recorded for the RTX 5070 Ti Mobile.

The RTX 5070 Ti Mobile has a recorded average benchmark score of 35,435 across nine tests. Its percentile ranking against all GPUs in the database is 80, placing it in the upper quintile of recorded hardware. The nearest rivals in the database provide context: the NVIDIA Quadro GV100 scores 35,520, which is 0.2% higher than the RTX 5070 Ti Mobile, making the difference essentially negligible. The AMD Radeon Pro Duo scores 35,860, a 1.2% advantage over the RTX 5070 Ti Mobile. The NVIDIA T1000 scores 36,289, 2.4% higher. Only the NVIDIA A2 scores lower at 34,690, representing a 2.1% deficit relative to the RTX 5070 Ti Mobile.

The individual benchmark results for the RTX 5070 Ti Mobile show its strongest recorded performance in Passmark G3D with a score of 24,004. The Geekbench OpenCL score of 143,870 and Geekbench Vulkan score of 139,213 are the highest raw numbers in the dataset, though these tests use different scaling than the Passmark suite. Passmark GPU Compute records 10,101. The DirectX tests show scores of 151 for DirectX 10, 237 for DirectX 11, 102 for DirectX 12, and 259 for DirectX 9. The 2D graphics test records 981.

The AMD Instinct MI300A has no benchmark scores recorded in the database. Its average benchmark score is 0, and its percentile ranking is 50. The nearest rivals field is empty. This means the database contains no measurable performance data for the MI300A, making direct numeric comparison impossible. The analysis must therefore focus on architectural specifications and the interpretative weight of those specifications.

Architecture Differences

The AMD Instinct MI300A and NVIDIA GeForce RTX 5070 Ti Mobile represent fundamentally different design philosophies. The MI300A uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm TSMC process. The RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on the GB205 chip, also built on a 5 nm TSMC process. Both share the same process node and foundry, but the transistor counts diverge dramatically.

The MI300A integrates 153,000 million transistors on a die size of 1,017 mm². This produces a transistor density of 150.4 million transistors per mm². The RTX 5070 Ti Mobile integrates 31,100 million transistors on a 263 mm² die, yielding a density of 118.3 million per mm². The MI300A's die is nearly four times larger in area and contains nearly five times as many transistors. This scale difference suggests the MI300A is designed for compute density at massive scale, while the RTX 5070 Ti Mobile prioritizes efficiency within a constrained mobile form factor.

The memory subsystems could not be more different. The MI300A carries 128 GB of HBM3 memory on an 8,192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 5070 Ti Mobile carries 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s. The MI300A's memory bandwidth is approximately 7.9 times higher, and its capacity is over 10 times greater. The memory clock rates reflect this: the MI300A runs at 1,300 MHz with 5.2 Gbps effective, while the RTX 5070 Ti Mobile runs at 1,750 MHz with 28 Gbps effective. The GDDR7 on the NVIDIA part achieves higher per-pin data rates, but the HBM3 on the AMD part wins decisively on aggregate bandwidth.

The compute resources also differ sharply. The MI300A has 14,592 shading units, 912 texture mapping units, and zero ROPs. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The MI300A's pixel rate is recorded as 0 MPixel/s, consistent with its lack of ROPs, while the RTX 5070 Ti Mobile delivers 115.8 GPixel/s. Texture rate favors the MI300A at 1,915.2 GTexel/s versus 266.2 GTexel/s for the NVIDIA part. FP32 compute shows 61.29 TFLOPS for the MI300A versus 17.04 TFLOPS for the RTX 5070 Ti Mobile, a 3.6x advantage for the AMD accelerator.

The RTX 5070 Ti Mobile includes 46 ray tracing cores and 184 tensor cores, features entirely absent from the MI300A's specification sheet. The NVIDIA part also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300A lists N/A for all three APIs. The power envelopes differ by an order of magnitude: the MI300A has a 750 W TDP with a suggested PSU of 1,150 W, while the RTX 5070 Ti Mobile has a 60 W TDP and no suggested PSU. The MI300A is an OAM module with no display outputs and no power connectors listed. The RTX 5070 Ti Mobile is an IGP with display outputs described as "Portable Device Dependent."

The Verdict

The data presents two products with almost no overlap in intended function. The AMD Instinct MI300A is a server-class accelerator with massive memory capacity, extreme bandwidth, and enormous compute throughput. The NVIDIA GeForce RTX 5070 Ti Mobile is a mobile graphics processor with ray tracing support, conventional display output, and a fraction of the power requirement.

The MI300A wins decisively on compute specifications: 3.6 times the FP32 throughput, 7.9 times the memory bandwidth, nearly five times the transistor count, and over ten times the memory capacity. It also has a higher boost clock at 2,100 MHz versus 1,447 MHz. However, the MI300A has no display outputs, no API support listed, no ROPs, and no ray tracing or tensor cores. It cannot render to a screen and has no recorded benchmark scores in the database.

The RTX 5070 Ti Mobile wins on every graphics-specific metric. It has 80 ROPs versus zero, 115.8 GPixel/s versus 0 MPixel/s, and full support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 60 W TDP is 12.5 times lower than the MI300A's 750 W. It has recorded benchmark scores and a percentile ranking of 80, placing it ahead of 80% of all GPUs in the database. Its nearest rivals cluster within 2.4% of its average score, indicating tight competition in its performance class.

The release dates show a generational gap: the MI300A launched on December 5, 2023, while the RTX 5070 Ti Mobile launched on February 28, 2025. The MI300A's predecessor is Radeon Instinct, while the RTX 5070 Ti Mobile's predecessor is GeForce 40 Mobile. Neither has a successor listed.

Where Each One Wins

The AMD Instinct MI300A wins in scenarios requiring massive memory and compute throughput. Its 128 GB HBM3 pool and 5.32 TB/s bandwidth suit workloads that need to keep large datasets resident on the accelerator. Its 61.29 TFLOPS of FP32 compute and 1,915.2 GTexel/s texture rate indicate a device built for sustained computational throughput rather than interactive rendering. The 1,017 mm² die and 153,000 million transistors confirm a design optimized for raw processing density. The 750 W TDP and 1,150 W suggested PSU indicate a system-level component for dedicated compute nodes, not a user-facing graphics solution.

The NVIDIA GeForce RTX 5070 Ti Mobile wins in all interactive graphics and consumer-facing scenarios. Its 80 ROPs and 115.8 GPixel/s pixel rate enable conventional rasterization. The 46 ray tracing cores and 184 tensor cores provide dedicated hardware for ray-traced lighting and AI-accelerated features. The DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API support make it compatible with standard graphics software stacks. The 60 W TDP fits within mobile power budgets, and its "Portable Device Dependent" display outputs indicate integration into laptops or similar portable hardware. The recorded benchmark scores, including 24,004 in Passmark G3D and 143,870 in Geekbench OpenCL, demonstrate measurable real-world performance in the database.

The RTX 5070 Ti Mobile's nearest rivals show its competitive position: the Quadro GV100 at 0.2% higher, the Radeon Pro Duo at 1.2% higher, the T1000 at 2.4% higher, and the A2 at 2.1% lower. These margins are narrow, indicating the RTX 5070 Ti Mobile sits in a tightly packed performance band. The MI300A has no comparable data points in the database, so its competitive position cannot be quantified.

The FP16 specification also differentiates the two. The RTX 5070 Ti Mobile lists FP16 at 17.04 TFLOPS with a 1:1 ratio to FP32. The MI300A lists no FP16 figure. This absence suggests either the data was not recorded or the architecture handles FP16 differently, but the database does not clarify which.

The production status field also differs: the RTX 5070 Ti Mobile is marked "Active," while the MI300A has no production status listed. This may indicate availability differences, but the database does not elaborate on what the missing field means for the MI300A.

The ROP count of zero for the MI300A is the most striking specification difference. Combined with no display outputs and N/A API support, it confirms the MI300A is not intended for any graphical output. The NVIDIA part, with its full ROP complement and display capability, is the only one of the two that can present images to a user. The data therefore supports a clear functional split: the MI300A for compute acceleration without display, the RTX 5070 Ti Mobile for graphics with display. Each wins in its respective domain, and neither specification sheet suggests overlap.
