AMD Instinct MI300 vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

Head-to-Head Benchmarks

The recorded benchmark data for this comparison is unusually sparse. The AMD Instinct MI300 has no benchmark scores in the database, while the NVIDIA GeForce RTX 5070 Ti SUPER has exactly one recorded result. That single data point comes from the 3DMark Steel Nomad DX12 test, where the RTX 5070 Ti SUPER scored 6269.5 points. With no head-to-head benchmark entries and no wins recorded for either side, the quantitative comparison rests entirely on this lone measurement.

The RTX 5070 Ti SUPER's average benchmark score sits at 6270, placing it in the 36th percentile among all GPUs in the database. Its nearest rivals show a tightly clustered group. The NVIDIA GeForce RTX 4070 Ti SUPER AD102 matches it exactly with a 0% delta, scoring 6270 as well. The AMD FirePro W600 comes in at 6223, which is 0.8% lower. The NVIDIA Quadro K620 posts 6282, 0.2% above. The AMD Radeon R7 M350 leads the group with 6327, sitting 0.9% higher than the RTX 5070 Ti SUPER. These deltas are all within a single percentage point, indicating that the RTX 5070 Ti SUPER's benchmark performance lands in a narrow competitive band.

What the data does not show is any comparable measurement for the MI300. The Instinct card has a percentile ranking of 50, yet its average benchmark score is recorded as zero. That combination suggests the percentile figure is derived from specification-based estimates rather than actual test runs. The absence of benchmark entries means the database contains no direct evidence of how the MI300 performs in the same Steel Nomad workload. Any conclusion about relative gaming or compute performance must come from architectural analysis rather than measured results.

Architecture Differences

The two cards diverge fundamentally in their design goals. The AMD Instinct MI300 uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built for data center compute workloads. The NVIDIA GeForce RTX 5070 Ti SUPER uses Blackwell 2.0 on the GB203 die, targeting consumer graphics. Both use a 5 nm process from TSMC, but the similarities end there.

The transistor counts reveal the scale gap. The MI300 packs 153,000 million transistors across a 1017 mm² die, yielding a density of 150.4 million transistors per square millimeter. The RTX 5070 Ti SUPER contains 45,600 million transistors on a 378 mm² die, with a density of 120.6 million per square millimeter. The MI300 has more than three times the transistor budget, but the RTX 5070 Ti SUPER achieves higher clock speeds. The NVIDIA card runs at a 2295 MHz base and 2452 MHz boost, while the MI300 operates at 1000 MHz base and 1700 MHz boost.

Memory configurations could not be more different. The MI300 carries 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 5070 Ti SUPER has 16 GB of GDDR7 on a 256-bit bus, providing 896.0 GB/s. The MI300's memory bandwidth is nearly six times higher, though the NVIDIA card's GDDR7 runs at a much faster effective speed of 28 Gbps compared to the MI300's 5.2 Gbps. The bus width difference, 8192 bits versus 256 bits, explains the bandwidth gap.

Compute resources follow different philosophies. The MI300 has 14,080 shading units, 880 texture mapping units, and zero ROPs. The RTX 5070 Ti SUPER has 8,960 shading units, 280 TMUs, and 96 ROPs. The MI300's pixel rate is recorded as 0 MPixel/s, which aligns with its lack of display outputs. The RTX 5070 Ti SUPER renders at 235.4 GPixel/s and textures at 686.6 GTexel/s, while the MI300 textures at 1,496.0 GTexel/s. The MI300's FP32 compute reaches 47.87 TFLOPS, slightly ahead of the RTX 5070 Ti SUPER's 43.94 TFLOPS. Both maintain a 1:1 ratio for FP16, with the MI300 at 47.87 TFLOPS and the NVIDIA card at 43.94 TFLOPS.

The RTX 5070 Ti SUPER includes 70 RT cores and 280 tensor cores, while the MI300 lists neither. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 lists N/A for all three APIs, confirming its lack of graphics rendering capability. The MI300 has no display outputs at all, while the RTX 5070 Ti SUPER provides 1x HDMI 2.1b and 3x DisplayPort 2.1b.

The Verdict

The data paints a clear picture of two cards built for entirely different purposes. The AMD Instinct MI300 is a data center compute accelerator. Its 128 GB of HBM3, 8192-bit bus, 5.32 TB/s bandwidth, and 47.87 TFLOPS of FP32 compute target massive parallel workloads. The absence of display outputs and graphics API support confirms it is not intended for rendering to a screen. The 600 W TDP and 2x 8-pin power connectors reflect its server-oriented design.

The NVIDIA GeForce RTX 5070 Ti SUPER is a consumer graphics card. Its 16 GB of GDDR7, 256-bit bus, 896.0 GB/s bandwidth, and 43.94 TFLOPS of FP32 compute serve gaming and workstation rendering. The 96 ROPs, 70 RT cores, 280 tensor cores, and full graphics API support enable the display output and rendering pipeline the MI300 lacks. The 350 W TDP and 1x 16-pin connector fit a desktop power envelope.

Who should pick which depends entirely on the workload. The MI300 suits compute-heavy environments where memory capacity and bandwidth dominate, such as large model training or scientific simulation. The RTX 5070 Ti SUPER suits interactive graphics, ray tracing, and general desktop use. The benchmark data does not directly compare them, because they do not compete in the same arena. The RTX 5070 Ti SUPER's single Steel Nomad result shows it performs on par with its immediate peers, but no such measurement exists for the MI300. The MI300's 50th percentile ranking appears spec-based rather than test-derived, given its zero average benchmark score.

For gaming and consumer rendering, the RTX 5070 Ti SUPER is the only viable option between the two. For server compute, the MI300's specifications indicate far greater memory resources and bandwidth, though its lack of benchmark entries leaves its measured performance unverified in the database.

Where Each One Wins

The AMD Instinct MI300 wins decisively in memory capacity, holding 128 GB versus the RTX 5070 Ti SUPER's 16 GB. Its 8192-bit memory bus and 5.32 TB/s bandwidth dwarf the NVIDIA card's 256-bit bus and 896.0 GB/s. The MI300 also leads in shading units at 14,080 versus 8,960, texture units at 880 versus 280, and texture rate at 1,496.0 GTexel/s versus 686.6 GTexel/s. Its FP32 compute of 47.87 TFLOPS edges past the RTX 5070 Ti SUPER's 43.94 TFLOPS. The MI300 has more transistors, 153,000 million versus 45,600 million, and a larger die at 1017 mm² versus 378 mm².

The NVIDIA GeForce RTX 5070 Ti SUPER wins in clock speeds, running at 2295 MHz base and 2452 MHz boost versus the MI300's 1000 MHz and 1700 MHz. It has 96 ROPs where the MI300 has none, plus 70 RT cores and 280 tensor cores that the MI300 lacks entirely. The NVIDIA card delivers 235.4 GPixel/s pixel rate while the MI300 records 0 MPixel/s. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300 lists N/A for all. The RTX 5070 Ti SUPER has display outputs, the MI300 has none. Power consumption favors the NVIDIA card at 350 W versus 600 W. The RTX 5070 Ti SUPER is longer at 304 mm versus 267 mm and taller at 137 mm versus 111 mm, but occupies a dual-slot form factor while the MI300's slot width is unlisted.

The MI300 suits workloads that demand massive memory pools and extreme bandwidth, such as large-scale data processing. The RTX 5070 Ti SUPER suits rendering tasks that require rasterization, ray tracing, and tensor operations. The MI300's higher FP32 throughput gives it an edge in raw compute, but that advantage comes without any graphics capability. The RTX 5070 Ti SUPER's lower power draw and complete display interface make it the practical choice for desktop systems. The MI300's 1000 W suggested PSU and 600 W TDP indicate a power-hungry installation, while the RTX 5070 Ti SUPER's power requirements are not even listed for a suggested PSU. The data shows two specialized tools, each winning in its own domain.
