AMD Instinct MI308X vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

The Verdict

The recorded data presents two accelerators with fundamentally different design targets. The AMD Instinct MI308X is a compute-oriented accelerator module with no display outputs and no graphics API support, while the NVIDIA GeForce RTX 5070 Ti SUPER is a client graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. For rendering, gaming, or any workload requiring a display connection, the data clearly points to the NVIDIA card. For large-scale compute tasks that can use 192 GB of HBM3 memory and an 8192-bit memory bus, the AMD module is the only option between the two. The NVIDIA card holds a 36th percentile ranking among all GPUs in the database, while the AMD module has no recorded benchmark scores and sits at the 50th percentile by default. The AMD module is a server-side compute device with no consumer-facing features, whereas the NVIDIA card is an active production product with a launch MSRP of 749 USD.

Architecture Differences

The AMD Instinct MI308X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated by TSMC on a 5 nm process. The die contains 153,000 million transistors across a 1017 mm² package, resulting in a transistor density of 150.4M per mm². The NVIDIA GeForce RTX 5070 Ti SUPER uses the GB203 chip on Blackwell 2.0 architecture, also fabricated by TSMC on a 5 nm process. Its die contains 45,600 million transistors across 378 mm², for a density of 120.6M per mm².

The AMD module integrates 19,456 shading units and 1,216 texture mapping units, but has zero ROPs and a pixel rate of 0 MPixel/s. It has no ray tracing cores and no tensor cores listed in the database. The NVIDIA card has 8,960 shading units, 280 TMUs, and 96 ROPs, with a pixel rate of 235.4 GPixel/s. It includes 70 ray tracing cores and 280 tensor cores. The AMD module has no graphics API support: DirectX, OpenGL, and Vulkan are all marked N/A. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Memory architecture diverges sharply. The AMD module uses 192 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The NVIDIA card uses 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s. The AMD module is an OAM module with no power connectors and no display outputs, requiring a suggested PSU of 1150 W. The NVIDIA card is a dual-slot design, 304 mm long, 137 mm tall, and 48 mm wide, using a single 16-pin connector, with 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two devices. The AMD Instinct MI308X has an empty benchmark array and an average benchmark score of 0. The NVIDIA GeForce RTX 5070 Ti SUPER has one recorded result: 6269.5 in 3DMark Steel Nomad DX12, with an average score of 6270.

The NVIDIA card's nearest rivals in the database provide context for its performance tier. The GeForce RTX 4070 Ti SUPER AD102 scores 6270, exactly matching the RTX 5070 Ti SUPER with a delta of 0%. The NVIDIA Quadro K620 scores 6282, which is 0.2% higher. The AMD FirePro W600 scores 6223, which is 0.8% lower than the RTX 5070 Ti SUPER. The AMD Radeon R7 M350 scores 6327, which is 0.9% higher. These deltas are all within a 1% band, indicating that the RTX 5070 Ti SUPER's single recorded benchmark places it in a performance cluster with these four other cards.

The AMD module cannot be compared numerically in any benchmark because no scores exist for it. Its 50th percentile ranking among all GPUs is a placeholder value, not derived from measured performance. The NVIDIA card's 36th percentile is based on actual recorded benchmark data. The absence of any benchmark results for the AMD module means the database contains no evidence of its compute performance relative to the NVIDIA card.

Specification Differences

The two devices differ in nearly every recorded specification field. The AMD module uses CDNA 3.0 architecture on the Aqua Vanjaram chip, while the NVIDIA card uses Blackwell 2.0 on the GB203 chip. The AMD module is in the Instinct (MIx) generation; the NVIDIA card is in the GeForce 50 generation.

Clock speeds differ significantly. The AMD module has a base clock of 1000 MHz and a boost clock of 2100 MHz, with memory clocked at 1300 MHz (5.2 Gbps effective). The NVIDIA card has a base clock of 2295 MHz and a boost clock of 2452 MHz, with memory clocked at 1750 MHz (28 Gbps effective).

Compute throughput shows the AMD module's advantage in raw numbers. The AMD module delivers 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1). The NVIDIA card delivers 43.94 TFLOPS FP32 and 43.94 TFLOPS FP16 (1:1). The AMD module's texture rate is 2,553.6 GTexel/s versus 686.6 GTexel/s for the NVIDIA card. The NVIDIA card's pixel rate is 235.4 GPixel/s, while the AMD module has none.

Power and physical specifications diverge completely. The AMD module has a TDP of 750 W and requires a suggested PSU of 1150 W, with no power connectors because it is an OAM module. The NVIDIA card has a TDP of 350 W, uses a single 16-pin connector, and lists no suggested PSU. The AMD module has no dimensions recorded and no display outputs. The NVIDIA card is 304 mm by 137 mm by 48 mm, dual-slot, with HDMI and DisplayPort outputs.

Memory capacity and bandwidth are the largest practical differences. The AMD module has 192 GB of HBM3 with 5.32 TB/s bandwidth on an 8192-bit bus. The NVIDIA card has 16 GB of GDDR7 with 896.0 GB/s bandwidth on a 256-bit bus. The AMD module has 8,960 more shading units, 936 more TMUs, and 936 more texture units than the NVIDIA card, but the NVIDIA card has 96 ROPs where the AMD module has none.

The release dates differ by roughly two years. The AMD module was released on December 5, 2023. The NVIDIA card has a release date of December 31, 2025, and its production status is listed as Active. The AMD module has no recorded production status. The NVIDIA card has a launch MSRP of 749 USD; the AMD module has no launch MSRP recorded.

Where Each One Wins

The AMD Instinct MI308X wins in raw compute resources. Its FP32 throughput of 81.72 TFLOPS is 85.9% higher than the NVIDIA card's 43.94 TFLOPS. Its texture rate of 2,553.6 GTexel/s is more than 3.7 times the NVIDIA card's 686.6 GTexel/s. Memory capacity is twelve times larger at 192 GB versus 16 GB, and memory bandwidth is nearly six times higher at 5.32 TB/s versus 896.0 GB/s. The 8192-bit memory bus is 32 times wider than the NVIDIA card's 256-bit bus. These specifications suit workloads that fit large models or datasets in memory and require maximum memory bandwidth.

The NVIDIA GeForce RTX 5070 Ti SUPER wins in every client-facing category. It has display outputs, a 235.4 GPixel/s pixel rate, 96 ROPs, 70 ray tracing cores, and 280 tensor cores, none of which exist on the AMD module. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the AMD module supports no graphics APIs. Its base clock of 2295 MHz and boost clock of 2452 MHz are more than double the AMD module's base clock of 1000 MHz, though the AMD module's boost clock of 2100 MHz is closer. The NVIDIA card is a dual-slot PCIe card with a 16-pin connector, while the AMD module requires an OAM slot and a 1150 W suggested PSU.

The NVIDIA card also has the only measured performance data. Its 3DMark Steel Nomad DX12 score of 6269.5 places it in a tight cluster with the RTX 4070 Ti SUPER AD102 at 6270, the Quadro K620 at 6282, the FirePro W600 at 6223, and the Radeon R7 M350 at 6327, all within a 1% band. The AMD module has no benchmark scores in the database, so no measured performance comparison is possible.

Power consumption favors the NVIDIA card. Its 350 W TDP is less than half the AMD module's 750 W TDP. The NVIDIA card is also physically smaller at 304 mm by 137 mm by 48 mm, versus the AMD module's unrecorded dimensions. The AMD module's transistor count of 153,000 million is more than three times the NVIDIA card's 45,600 million, and its die size of 1017 mm² is nearly three times the NVIDIA card's 378 mm².

The use case split is clear from the data. The AMD Instinct MI308X targets compute environments where memory capacity, memory bandwidth, and FP32 throughput are the primary requirements, and where display output and graphics API support are irrelevant. The NVIDIA GeForce RTX 5070 Ti SUPER targets client systems that render graphics, support ray tracing and tensor operations, connect to displays, and run within a 350 W power envelope. The database contains no evidence that the AMD module can perform any graphics or display task, and no evidence that the NVIDIA card can match the AMD module's memory capacity or bandwidth. Each device wins in its own domain, and the specifications do not overlap.
