AMD Radeon RX 9050 vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The database records contain no direct head-to-head benchmark entries for the AMD Radeon RX 9050 against the NVIDIA B200 SXM6. Both products sit at the 50th percentile versus all GPUs in the database, and neither has an average benchmark score recorded. Without measured performance deltas, the comparison must rely entirely on the architectural and specification data captured for each part.

The raw compute figures show a wide gap. The NVIDIA B200 SXM6 delivers 69.34 TFLOPS FP32 and 69.34 TFLOPS FP16, while the AMD Radeon RX 9050 delivers 10.65 TFLOPS FP32 and 10.65 TFLOPS FP16. That places the B200 at roughly 6.5 times the FP32 throughput of the RX 9050, a difference driven by the B200's 18,944 shading units against the RX 9050's 1,024. Texture rate follows the same pattern: the B200 reaches 1,083.4 GTexel/s, the RX 9050 reaches 166.4 GTexel/s.

Pixel throughput inverts the trend. The RX 9050 produces 166.4 GPixel/s, while the B200 SXM6 produces only 43.92 GPixel/s. The RX 9050's 64 ROPs outperform the B200's 24 ROPs in rasterization work, an unusual result for a comparison that otherwise favors the server part by a massive margin. This indicates the two products are built for entirely different workloads, and a single aggregate benchmark score would obscure that split.

Memory capacity and bandwidth also separate the two decisively. The B200 SXM6 carries 180 GB of HBM3e across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The RX 9050 carries 8 GB of GDDR6 across a 128-bit bus, yielding 288.0 GB/s. The B200's memory bandwidth advantage is roughly 28 times that of the RX 9050, and its capacity advantage is 22.5 times. The RX 9050's memory clock runs at 2250 MHz with 18 Gbps effective, while the B200 runs at 2000 MHz with 8 Gbps effective, but the B200's vastly wider bus makes the effective bandwidth comparison one-sided.

Clock speeds tell a different story. The RX 9050 has a base clock of 1330 MHz and a boost clock of 2600 MHz, with a game clock of 1920 MHz. The B200 SXM6 has a base clock of just 120 MHz and a boost clock of 1830 MHz. The RX 9050's boost clock is 42% higher than the B200's boost clock, and its base clock is more than 11 times higher. The B200 compensates with sheer scale: 592 texture mapping units, 592 tensor cores, and 29,700 million transistors on the AMD side versus 208,000 million on the NVIDIA side.

The B200 SXM6 also leads in transistor density per square millimeter when measured by absolute count: 127.8M per mm² on a 1628 mm² die, versus 149.2M per mm² on the RX 9050's 199 mm² die. The RX 9050 packs transistors more densely, but the B200's die is over eight times larger, allowing the NVIDIA part to house nearly seven times more transistors overall.

Where Each One Wins

The AMD Radeon RX 9050 wins in use cases that depend on rasterization throughput, clock speed, and conventional display output. Its 166.4 GPixel/s pixel rate is nearly four times that of the B200 SXM6. Its 64 ROPs handle traditional framebuffer work, and its boost clock of 2600 MHz gives it a latency advantage in lightly threaded rendering loops. The RX 9050 also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a functional graphics card for client workloads. Its display outputs include 1x HDMI 2.1b and 2x DisplayPort 2.1a, so it can drive monitors directly, something the B200 cannot do. The RX 9050's 92 W TDP and 250 W suggested PSU also fit within a conventional desktop power envelope, and its dual-slot, 1x 8-pin design is standard for consumer hardware.

The NVIDIA B200 SXM6 wins in compute-density scenarios, which is the intended domain of a server accelerator. Its 69.34 TFLOPS FP32 and FP16 throughput, 8.19 TB/s memory bandwidth, and 180 GB capacity make it suitable for large-scale parallel workloads that saturate memory and compute resources simultaneously. The B200's 592 tensor cores give it a hardware path for matrix operations, while the RX 9050 has no tensor core count recorded in the database. The B200 also uses PCIe 6.0 x16, double the bus generation of the RX 9050's PCIe 5.0 x16, which matters for data movement in multi-GPU server configurations. Its SXM Module form factor and 1000 W TDP reflect a design meant for dense server chassis with dedicated cooling, not standalone graphics.

The transistor budgets reinforce this split. The B200's 208,000 million transistors on a 1628 mm² die are allocated toward massive compute arrays and HBM3e stacks. The RX 9050's 29,700 million transistors on a 199 mm² die are allocated toward a balanced rasterization pipeline with 64 TMUs and 64 ROPs. The RX 9050's RDNA 4.0 architecture with 16 ray tracing cores targets real-time graphics, while the B200's Blackwell architecture targets data-center acceleration with no display outputs and no graphics API support listed.

The Verdict

The data directs each product to a different buyer. The AMD Radeon RX 9050 is a client-side graphics card: it has display outputs, a high pixel rate, a 2600 MHz boost clock, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 50th percentile ranking against all GPUs places it in the middle of the database's performance distribution, and its 8 GB memory capacity and 288.0 GB/s bandwidth suit conventional gaming and desktop rendering workloads. The 92 W TDP and 250 W suggested PSU make it a low-power option, and the dual-slot cooler with a single 8-pin connector is straightforward to install.

The NVIDIA B200 SXM6 is a server accelerator with a 1000 W TDP, a 1400 W suggested PSU, and an SXM Module form factor that requires a compatible server platform. Its 180 GB HBM3e memory and 8.19 TB/s bandwidth dominate the memory hierarchy comparison, and its 69.34 TFLOPS FP32 throughput is the highest compute figure in this matchup. It has no display outputs and no graphics API support, confirming it is not a graphics card in the conventional sense. Its 50th percentile ranking against all GPUs is identical to the RX 9050, but that percentile is computed across a database that mixes client and server parts, so it does not reflect the two products' relative standing within their respective categories.

The launch MSRP for the B200 SXM6 is 34,999 USD. No launch MSRP is recorded for the RX 9050.

Architecture Differences

The two GPUs come from different architectural lineages and are fabricated on different process nodes. The AMD Radeon RX 9050 uses the Navi 44 chip built on RDNA 4.0 architecture, part of the Navi IV (RX 9000) generation. It is manufactured on a 4 nm process at TSMC. The NVIDIA B200 SXM6 uses the GB100 chip built on Blackwell architecture, part of the Server Blackwell (Bxx) generation. It is manufactured on a 5 nm process at TSMC.

Transistor counts diverge sharply. The RX 9050 contains 29,700 million transistors on a 199 mm² die, yielding a transistor density of 149.2M per mm². The B200 SXM6 contains 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8M per mm². The RX 9050 has the higher density, but the B200's much larger die gives it the overall transistor advantage.

Memory architecture differs fundamentally. The RX 9050 uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The B200 SXM6 uses 180 GB of HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The RX 9050's memory clock is 2250 MHz (18 Gbps effective), while the B200's is 2000 MHz (8 Gbps effective).

Compute unit configurations reflect their respective purposes. The RX 9050 has 1,024 shading units, 64 TMUs, 64 ROPs, and 16 ray tracing cores. The B200 SXM6 has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The RX 9050's ROP count is higher, while the B200 dominates in shading units, TMUs, and tensor cores.

Clock behavior also differs. The RX 9050 has a base clock of 1330 MHz, a game clock of 1920 MHz, and a boost clock of 2600 MHz.
