Architecture Differences

The two GPUs represent opposite ends of the design spectrum. The AMD Radeon 740M is built on the RDNA 3.0 architecture, manufactured on a 4 nm process at TSMC. It uses the Phoenix2 chip, belongs to the Navi III IGP generation, and is an integrated graphics processor (IGP) with a PCIe 4.0 x8 bus interface. It has no power connectors and relies on the motherboard for display outputs.

The NVIDIA B200 SXM6 is built on the Blackwell architecture, manufactured on a 5 nm process at TSMC. It uses the GB100 chip, belongs to the Server Blackwell generation, and is a dedicated SXM module. It connects via PCIe 6.0 x16 and has no display outputs whatsoever, as it is designed for server compute workloads.

The Radeon 740M has 256 shading units, 16 texture mapping units, and 8 ROPs. It also includes 4 ray tracing cores but no tensor cores. The B200 SXM6 has 18,944 shading units, 592 TMUs, and 24 ROPs. It includes 592 tensor cores but no dedicated ray tracing cores listed in the data. The B200's tensor core count is a defining feature, enabling its AI and deep learning focus.

The Radeon 740M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not oriented toward traditional graphics APIs. This is a fundamental architectural divergence: one is a client-side integrated GPU for graphics, the other is a server-side accelerator for compute and AI workloads.

Clock behavior also differs significantly. The Radeon 740M runs at a base clock of 800 MHz and boosts to 2800 MHz. The B200 SXM6 has an extremely low base clock of 120 MHz but boosts to 1830 MHz. The low base clock on the B200 is characteristic of a power-constrained server part that spends most of its time at boost under load.

Where Each One Wins

The AMD Radeon 740M wins in scenarios that require an integrated graphics solution with low power draw. Its 45 W TDP makes it suitable for thin-and-light laptops or small form factor systems where a discrete GPU is not feasible. It supports modern graphics APIs, has display outputs via the motherboard, and is positioned for everyday graphics, light gaming, and media acceleration. Its benchmark presence is confirmed by a Geekbench OpenCL score of 10,172 and a Geekbench Vulkan score of 15,568.

The NVIDIA B200 SXM6 wins decisively in raw compute throughput, memory bandwidth, and capacity. Its 69.34 TFLOPS of FP32 and 69.34 TFLOPS of FP16 (1:1) make it a server-class accelerator. The 180 GB HBM3e memory with 8.19 TB/s bandwidth is an order of magnitude beyond what an IGP can access. The presence of 592 tensor cores positions it for AI inference, training, and scientific computing. Its 1000 W TDP and 1400 W suggested PSU indicate a data center deployment scenario.

The B200 also wins on texture rate, delivering 1,083.4 GTexel/s versus the Radeon's 44.80 GTexel/s. Pixel rate favors the B200 as well, at 43.92 GPixel/s versus 22.40 GPixel/s. The Radeon 740M wins on transistor density, with 152.6M transistors per mm² versus the B200's 127.8M per mm², reflecting the tighter 4 nm process.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, and the B200 SXM6 has no recorded benchmark entries. However, the Radeon 740M has two recorded scores: 10,172 in Geekbench OpenCL and 15,568 in Geekbench Vulkan. Its average benchmark score is 12,870, placing it in the 53rd percentile of all GPUs.

The B200 SXM6 has an average benchmark score of 0 and sits in the 50th percentile, but this is a function of missing data rather than performance. The nearest rivals of the Radeon 740M provide context: the AMD FirePro W5100 scores 12,847 (0.2% behind), the AMD Radeon Pro 455 scores 12,831 (0.3% behind), the NVIDIA GeForce GTX 590 scores 12,830 (0.3% behind), and the AMD Radeon RX 580 scores 12,928 (0.4% ahead). The Radeon 740M sits comfortably in this cluster, indicating parity with mid-range discrete GPUs from previous generations.

For the B200, no comparable benchmark data exists in the database. The specification comparison must stand in place of measured results. The FP32 delta between the two parts is substantial: 69.34 TFLOPS versus 2.867 TFLOPS. The B200's FP16 performance is identical to its FP32 at 69.34 TFLOPS (1:1), which is typical for compute-focused accelerators. The Radeon 740M also lists FP16 at 2.867 TFLOPS (1:1), showing it does not gain a throughput advantage in half precision.

The texture rate difference is the largest relative gap in the specification data: 1,083.4 GTexel/s versus 44.80 GTexel/s, a factor of roughly 24. The pixel rate gap is smaller but still significant, with the B200 at 43.92 GPixel/s versus 22.40 GPixel/s, a factor of about 2. The memory bandwidth gap is even more extreme: 8.19 TB/s versus System Dependent, which on an IGP is typically limited by system memory bandwidth.

The Verdict

The data describes two products with no meaningful overlap in purpose or performance envelope. The AMD Radeon 740M is an integrated GPU with a 45 W TDP, 256 shading units, and 2.867 TFLOPS of FP32 compute. It supports modern graphics APIs, has motherboard-dependent display outputs, and posts benchmark scores in the 53rd percentile of all GPUs, placing it near discrete cards like the Radeon RX 580. It is best suited for systems where power efficiency, compactness, and graphics API compatibility are the priorities.

The NVIDIA B200 SXM6 is a server accelerator with a 1000 W TDP, 18,944 shading units, 592 tensor cores, and 69.34 TFLOPS of FP32 compute. Its 180 GB HBM3e memory and 8.19 TB/s bandwidth are designed for large-scale compute tasks. It has no display outputs and no graphics API support, confirming it is not a graphics card in the traditional sense. Its launch MSRP is 34,999 USD.

For a user choosing between these two, the decision is dictated by the workload. If the requirement is a low-power integrated solution for a client system with graphics output, the Radeon 740M is the only viable option. If the requirement is maximum compute throughput, memory capacity, and tensor core availability for server workloads, the B200 SXM6 is the clear choice. The B200's FP32 output is over 24 times higher, its texture rate is over 24 times higher, and its memory subsystem is in a different class entirely.

The Radeon 740M has no tensor cores, while the B200 has 592. The B200 has no ray tracing cores, while the Radeon has 4. This tradeoff reflects their design intents: the Radeon targets graphics rendering and light compute, the B200 targets AI and high-performance computing. The Radeon 740M, with its 53rd percentile standing and near-parity with the Radeon RX 580, is a competent IGP. The B200, despite having no benchmark scores recorded, is positioned as a top-tier server accelerator by its specifications alone. The recorded data supports no other conclusion.
