AMD Instinct MI300 vs AMD Radeon RX 9060 XT LP Comparison

Head-to-Head Benchmarks

The AMD Instinct MI300 and the AMD Radeon RX 9060 XT LP occupy opposite ends of the accelerator spectrum, and the recorded data reflects this divide clearly. The most striking difference lies in raw compute throughput. The Instinct MI300 delivers 47.87 TFLOPS of FP32 performance, while the RX 9060 XT LP delivers 24.99 TFLOPS. This means the Instinct MI300 holds a 91.6% advantage in peak FP32 throughput. The texture rate tells a similar story: the MI300 produces 1,496.0 GTexel/s versus 390.4 GTexel/s for the RX 9060 XT LP, a 283% lead for the data center part.

Memory bandwidth is where the gap becomes extreme. The Instinct MI300 offers 5.32 TB/s of bandwidth across a 8192-bit bus, while the RX 9060 XT LP provides 322.3 GB/s over a 128-bit bus. The MI300 therefore has roughly 16.5 times the memory bandwidth of the RX 9060 XT LP. This is not a marginal difference; it is an order-of-magnitude separation that defines their respective workloads. The MI300 also carries 128 GB of HBM3 memory, compared to 16 GB of GDDR6 on the RX 9060 XT LP, an 8x capacity advantage.

The RX 9060 XT LP does win in certain measured areas. Its pixel rate is 195.2 GPixel/s, whereas the MI300 records 0 MPixel/s. This is a direct consequence of the MI300 having no ROPs, meaning it cannot perform traditional rasterization output. The RX 9060 XT LP also has 32 ray tracing cores, while the MI300 lists none. In real-world benchmark terms, the RX 9060 XT LP scores 88,183 in Geekbench OpenCL and 39,476 in Geekbench Vulkan. The MI300 has no recorded benchmark scores in the database, and its average benchmark score is listed as 0. This makes direct score comparison impossible, but the specification data provides the context for why these two products target entirely different segments.

Clock speeds also show a divergence in design philosophy. The RX 9060 XT LP operates at a 1380 MHz base clock and a 3050 MHz boost clock, with a game clock of 2450 MHz. The MI300 runs at 1000 MHz base and 1700 MHz boost. The RX 9060 XT LP's higher clocks suit bursty, latency-sensitive graphics workloads, while the MI300 relies on massive parallelism and memory throughput rather than clock speed.

The power envelope confirms the positioning. The MI300 has a 600 W TDP and requires a 1000 W suggested PSU, while the RX 9060 XT LP draws 140 W and needs only a 300 W PSU. The MI300 uses two 8-pin power connectors; the RX 9060 XT LP uses one. This 460 W difference in TDP is not a small detail: it dictates the physical platform requirements for each card.

The Verdict

The data points to two separate products with no meaningful overlap. The AMD Instinct MI300 is a compute accelerator designed for massive parallel workloads. Its 128 GB HBM3 memory, 8192-bit bus, and 47.87 TFLOPS FP32 performance make it a data center part. Its 600 W TDP, lack of display outputs, and absence of graphics APIs confirm this. The MI300 has no ROPs, no ray tracing cores, and no pixel output. It is not a graphics card in the conventional sense.

The AMD Radeon RX 9060 XT LP is a client graphics card. It has 64 ROPs, 32 ray tracing cores, a 195.2 GPixel/s pixel rate, and full support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. It outputs video through 1x HDMI 2.1b and 2x DisplayPort 2.1a. Its 140 W TDP and single 8-pin connector fit a desktop environment. Its average benchmark score of 63,830 places it in the 89th percentile of all GPUs, with its nearest rival, the NVIDIA CMP 30HX, scoring 63,842. The RX 9060 XT LP is essentially tied with that rival, within 0% delta.

The choice depends entirely on the workload. For FP32 compute density, memory bandwidth, and capacity, the MI300 dominates. For rasterization, ray tracing, and standard graphics API support, the RX 9060 XT LP is the only option of the two. The MI300 cannot output video, and the RX 9060 XT LP cannot match the MI300's memory subsystem. The recorded data shows no scenario where one substitutes for the other.

Specification Differences

The two cards differ in nearly every measured specification. The MI300 uses a 5 nm process, while the RX 9060 XT LP uses a 4 nm process. Both are fabricated by TSMC. The MI300 has 153,000 million transistors on a 1017 mm² die, while the RX 9060 XT LP has 29,700 million transistors on a 199 mm² die. Transistor density is nearly identical: 150.4M per mm² for the MI300 and 149.2M per mm² for the RX 9060 XT LP.

Clock speeds differ substantially. The MI300 runs at 1000 MHz base and 1700 MHz boost. The RX 9060 XT LP runs at 1380 MHz base, 2450 MHz game, and 3050 MHz boost. Memory clocks also differ: 1300 MHz (5.2 Gbps effective) for the MI300 versus 2518 MHz (20.1 Gbps effective) for the RX 9060 XT LP.

Shading units: 14,080 for the MI300 versus 2,048 for the RX 9060 XT LP. Texture mapping units: 880 versus 128. Raster output units: 0 versus 64. Ray tracing cores: none versus 32. The MI300 has no display outputs; the RX 9060 XT LP has 1x HDMI 2.1b and 2x DisplayPort 2.1a.

Power requirements are starkly different: 600 W TDP with 2x 8-pin connectors and a 1000 W suggested PSU for the MI300, versus 140 W TDP with 1x 8-pin connector and a 300 W suggested PSU for the RX 9060 XT LP. The MI300 is 267 mm long and 111 mm tall; the RX 9060 XT LP has no recorded dimensions but is listed as dual-slot. The MI300 has no production status listed; the RX 9060 XT LP is Active.

Architecture Differences

The MI300 uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, part of the Instinct (MIx) generation. The RX 9060 XT LP uses RDNA 4.0 on the Navi 44 chip, part of the Navi IV (RX 9000) series. These are fundamentally different architectures with different design goals.

CDNA 3.0 is optimized for compute acceleration. The MI300's 14,080 shading units and 880 TMUs feed its 47.87 TFLOPS FP32 throughput. It has no ROPs, which explains the 0 MPixel/s pixel rate. The 128 GB HBM3 memory with 5.32 TB/s bandwidth is the defining feature: this memory subsystem is built for large datasets that cannot fit in conventional GPU memory.

RDNA 4.0 is optimized for graphics rendering. The RX 9060 XT LP's 2,048 shading units, 128 TMUs, and 64 ROPs support its 195.2 GPixel/s pixel rate. Its 32 ray tracing cores enable hardware-accelerated ray tracing, a feature entirely absent from the MI300. The 16 GB GDDR6 memory and 322.3 GB/s bandwidth are typical for a client graphics card.

The process nodes differ: 5 nm for the MI300, 4 nm for the RX 9060 XT LP. Despite the smaller node, the RX 9060 XT LP has fewer transistors (29,700 million versus 153,000 million) and a smaller die (199 mm² versus 1017 mm²). The transistor densities are nearly equal, indicating that both chips are similarly dense, but the MI300's enormous die allows it to pack over 5 times more transistors.

The MI300's API support is listed as N/A for DirectX, OpenGL, and Vulkan. The RX 9060 XT LP supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This is a fundamental architectural difference: the MI300 is not designed to run graphics APIs, while the RX 9060 XT LP is fully equipped for them.

The bus interface is the same for both: PCIe 5.0 x16. The MI300's predecessor is listed as Radeon Instinct, while the RX 9060 XT LP's predecessor is Navi III. The MI300 was released on 2023-01-03, and the RX 9060 XT LP on 2025-12-16. The MI300's power connectors are 2x 8-pin, while the RX 9060 XT LP uses 1x 8-pin. The MI300 has no slot width listed; the RX 9060 XT LP is dual-slot. The MI300 has no launch MSRP recorded, and neither does the RX 9060 XT LP.
