AMD Instinct MI300X vs NVIDIA GeForce RTX 5070 Ti Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark recorded in the database is Geekbench OpenCL, and the result is decisive. The AMD Instinct MI300X scores 317,994, while the NVIDIA GeForce RTX 5070 Ti scores 212,363. That is a delta of 49.7% in favor of the AMD part, a substantial margin that reflects the fundamentally different positioning of these two products.

Looking at the MI300X's standing relative to its nearest rivals, the data shows it sits at the 100th percentile among all GPUs in the database. Its nearest competitor is the NVIDIA B200 with an average score of 345,482, which puts the MI300X 8% behind. The NVIDIA H200 NVL scores 334,891, placing the MI300X 5% behind that part as well. However, the MI300X beats the NVIDIA L40S (295,763) by 7.5% and the NVIDIA RTX 6000 Ada Generation (287,237) by 10.7%. These are the only comparable data points available, and they indicate that the MI300X belongs to a performance tier well above consumer or even professional workstation graphics cards.

The RTX 5070 Ti, by contrast, sits at the 86th percentile and has an average benchmark score of 49,957 across all its recorded tests. Its nearest rivals are older consumer flagships: the AMD Radeon RX 6900 XT (50,951) is 2% ahead, the AMD Radeon RX Vega 64 (50,001) is essentially tied at 0.1% ahead, and the Intel Arc A550M (49,737) is 0.4% behind. The AMD Radeon RX 6800 XT (48,477) trails the RTX 5070 Ti by 3.1%. These close deltas suggest the RTX 5070 Ti performs in the same band as previous-generation high-end consumer cards, which is a reasonable expectation for a new mid-range to upper-mid-range GeForce part.

What the head-to-head table shows is a single test, but the implications are broad. The MI300X's OpenCL score is roughly 50% higher than the RTX 5070 Ti's, and the surrounding rival data confirms that this gap is not an anomaly. The MI300X competes with server accelerators like the B200 and H200, not with graphics cards designed for desktop use. The RTX 5070 Ti competes with previous-generation Radeon flagships. These are different markets, different power envelopes, and different design goals.

Architecture Differences

The two chips come from different design lineages. The MI300X uses the Aqua Vanjaram chip with the CDNA 3.0 architecture, built for compute acceleration in data centers. The RTX 5070 Ti uses the GB203 chip with the Blackwell 2.0 architecture, designed for consumer graphics and gaming workloads.

The process nodes are nominally identical: both use 5 nm manufacturing at TSMC. But the scale of the silicon diverges sharply. The MI300X packs 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RTX 5070 Ti contains 45,600 million transistors on a 378 mm² die, with a density of 120.6 million per mm². The MI300X is more than twice as large in die area and more than three times the transistor count.

Shading unit counts reflect the same divide. The MI300X has 19,456 shading units and 1,216 texture mapping units, but no raster operation units (ROPs) and no dedicated ray tracing or tensor core counts recorded. Its pixel rate is listed as 0 MPixel/s, which confirms it does not perform traditional graphics rasterization. The RTX 5070 Ti has 8,960 shading units, 280 TMUs, and 96 ROPs, plus 70 ray tracing cores and 280 tensor cores. Its pixel rate is 235.4 GPixel/s.

The MI300X's texture rate is 2,553.6 GTexel/s, which is roughly 3.7 times the RTX 5070 Ti's 686.6 GTexel/s. FP32 compute follows a similar pattern: the MI300X delivers 81.72 TFLOPS versus 43.94 TFLOPS for the RTX 5070 Ti. Both achieve their FP16 throughput at a 1:1 ratio with FP32, so the MI300X also doubles its FP16 output to 81.72 TFLOPS, while the RTX 5070 Ti reaches 43.94 TFLOPS.

Memory architecture is another fundamental split. The MI300X uses HBM3 with 192 GB of capacity on an 8192-bit bus, yielding 5.32 TB/s of bandwidth. The RTX 5070 Ti uses GDDR7 with 16 GB on a 256-bit bus, providing 896.0 GB/s. The MI300X has 12 times the capacity and nearly 6 times the bandwidth. The MI300X memory clock is 1300 MHz (5.2 Gbps effective), while the RTX 5070 Ti runs at 1750 MHz (28 Gbps effective). The RTX 5070 Ti's memory is faster per pin, but the MI300X's enormous bus width overwhelms that advantage.

Clock speeds also differ. The MI300X has a base clock of 1000 MHz and a boost of 2100 MHz. The RTX 5070 Ti runs at 2295 MHz base and 2452 MHz boost. The consumer part operates at higher frequencies, but the server part compensates with far more compute units and memory parallelism.

Specification Differences

The recorded specifications show distinct profiles. The MI300X has a TDP of 750 W, while the RTX 5070 Ti is rated at 300 W. The MI300X uses an OAM module slot and has no power connectors listed, while the RTX 5070 Ti is dual-slot with a single 16-pin connector. The suggested power supply for the MI300X is 1150 W; for the RTX 5070 Ti it is 700 W.

Both use PCIe 5.0 x16 for the bus interface, so connectivity is on par. Display outputs differ completely: the MI300X has no outputs, while the RTX 5070 Ti provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The MI300X lists no graphics API support, while the RTX 5070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates these are not competing products. The MI300X is a compute accelerator with no display outputs, no graphics API support, and a 750 W power envelope. It exists for HPC and AI workloads that require massive memory capacity and bandwidth. The RTX 5070 Ti is a consumer graphics card with full display outputs, modern API support, and a 300 W TDP. It is designed for rendering, gaming, and general-purpose GPU compute.

For raw compute in OpenCL, the MI300X wins by 49.7%. Its 192 GB of HBM3 memory and 5.32 TB/s bandwidth are unmatched by the RTX 5070 Ti's 16 GB GDDR7 and 896.0 GB/s. The MI300X also sits at the 100th percentile in the database, while the RTX 5070 Ti is at the 86th. The nearest rival data reinforces this: the MI300X is grouped with server accelerators like the B200 and H200, while the RTX 5070 Ti is grouped with consumer Radeon cards from previous generations.

The RTX 5070 Ti has advantages in areas the MI300X does not address. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. It has 96 ROPs, 70 ray tracing cores, and 280 tensor cores. It produces 235.4 GPixel/s. It has a dual-slot form factor, a 16-pin power connector, and a suggested PSU of 700 W, all of which are compatible with desktop systems. The MI300X has no pixel rate to speak of and no graphics rendering capability.

Users who need a graphics card for a workstation or gaming PC should select the RTX 5070 Ti on the basis of its display outputs, API support, and lower power requirements. Users who need a compute accelerator for memory-intensive workloads should select the MI300X based on its 192 GB capacity, 5.32 TB/s bandwidth, and 49.7% OpenCL lead.

Where Each One Wins

The MI300X wins decisively in compute throughput. Its Geekbench OpenCL score of 317,994 is 49.7% higher than the RTX 5070 Ti's 212,363. Its FP32 output of 81.72 TFLOPS doubles the RTX 5070 Ti's 43.94 TFLOPS. Its texture rate of 2,553.6 GTexel/s is roughly 3.7 times faster. Its memory bandwidth of 5.32 TB/s is nearly 6 times higher than the RTX 5070 Ti's 896.0 GB/s. The MI300X also holds the 100th percentile ranking, meaning it outperforms virtually every other GPU in the database on average benchmark score.

The RTX 5070 Ti wins in every graphics-specific category. It has 96 ROPs, a pixel rate of 235.4 GPixel/s, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.
