AMD Radeon 680M vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Radeon 680M and the NVIDIA B200 SXM6. The database lists no shared test results for these two products, and neither unit has a win tally in direct competition. The Radeon 680M carries three individual benchmark scores, while the B200 SXM6 has no recorded benchmark entries at all.

The Radeon 680M posts a 3DMark Steel Nomad DX12 score of 378, a Geekbench OpenCL score of 23468, and a Geekbench Vulkan score of 21965. Its average benchmark score across recorded tests is 15270, placing it at the 57th percentile of all GPUs in the database. The B200 SXM6, by contrast, has an average benchmark score of 0 and sits at the 50th percentile, which reflects the absence of any recorded performance data rather than a measured performance level.

The Radeon 680M's nearest rivals in the database provide context for its standing. The NVIDIA GeForce GTX 580 averages 15283, a 0.1% difference from the 680M. The NVIDIA GeForce RTX 2060 averages 15290, also 0.1% higher. The NVIDIA GeForce RTX 3050 OEM averages 15199, which is 0.5% lower than the 680M. The AMD Radeon RX 7600 averages 15171, 0.7% lower. These deltas are small, indicating the 680M clusters tightly with a group of discrete desktop GPUs from several generations despite being an integrated part.

Because the B200 SXM6 has no benchmark scores and no nearest rivals listed, the database cannot establish its relative performance position through measured results. The percentile value of 50 is a neutral placeholder, not a performance verdict.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The AMD Radeon 680M uses the Rembrandt+ chip based on RDNA 2.0 architecture, from the Navi II IGP generation. It is built on a 6 nm process at TSMC. The NVIDIA B200 SXM6 uses the GB100 chip based on Blackwell architecture, from the Server Blackwell generation, built on a 5 nm process at TSMC.

Transistor density differs sharply. The Radeon 680M packs 13,100 million transistors into a 208 mm² die, yielding 63.0M transistors per mm². The B200 SXM6 packs 208,000 million transistors into a 1628 mm² die, yielding 127.8M transistors per mm². The B200's density is roughly double that of the 680M, which reflects the different process nodes and design objectives.

Shader resources are not remotely comparable. The Radeon 680M has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. It has no tensor cores listed. The B200 SXM6 has 18944 shading units, 592 texture mapping units, 24 ROPs, and 592 tensor cores. Its ray tracing core count is not listed. The B200 has roughly 24.7 times the shading units and 12.3 times the texture units of the 680M, although its ROP count is lower.

Compute throughput follows the same pattern. The Radeon 680M delivers 3.379 TFLOPS FP32 and 6.758 TFLOPS FP16 with a 2:1 ratio. The B200 SXM6 delivers 69.34 TFLOPS FP32 and 69.34 TFLOPS FP16 with a 1:1 ratio. The B200's FP32 output is about 20.5 times higher, and its FP16 output is roughly 10.3 times higher.

Pixel and texture rates show a different balance. The Radeon 680M achieves 70.40 GPixel/s and 105.6 GTexel/s. The B200 SXM6 achieves 43.92 GPixel/s and 1,083.4 GTexel/s. The B200's texture rate is over 10 times higher, but its pixel rate is lower because of its smaller ROP count.

Clock behavior also differs. The Radeon 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1830 MHz. The very low base clock on the B200 reflects a server-oriented power management approach, while the 680M's higher base clock suits a mobile integrated GPU.

API support diverges completely. The Radeon 680M lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for all three, indicating that it is not designed for conventional graphics API workloads.

Where Each One Wins

The AMD Radeon 680M wins in the only category where measured data exists: actual benchmark results. It has three recorded scores, an average benchmark score of 15270, and a 57th percentile standing among all GPUs. Its nearest rivals, all discrete desktop cards, sit within a narrow 1.4 percentage point band, which means the integrated 680M performs at a level comparable to those discrete options. Its low 50 W TDP, lack of power connectors, and portable device dependent display outputs position it for mobile and compact systems where power draw and physical space are constrained. Its DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support makes it usable in conventional graphics and gaming workloads.

The NVIDIA B200 SXM6 wins in raw hardware capability as listed in the specification data. It has far more shading units, texture units, tensor cores, memory capacity, memory bandwidth, and FP32 and FP16 throughput. Its 180 GB HBM3e memory with 8.19 TB/s bandwidth is a server-class memory subsystem. Its 1000 W TDP and 1400 W suggested PSU indicate a power-hungry, high-performance compute platform. Its PCIe 6.0 x16 interface and lack of display outputs confirm it is built for data center compute rather than graphics output. Its 592 tensor cores point toward AI and machine learning workloads, although no benchmark data in the database verifies performance.

The split is clean. The Radeon 680M is the only one of the two with measured performance data, and it is the only one with graphics API support. The B200 SXM6 is the only one with tensor cores, a large dedicated memory pool, and a server-class power envelope. The database records no overlapping test results, so any direct comparison of performance must rely on the specification differences rather than measured outcomes. The 680M's position at the 57th percentile with an average score of 15270 places it among mid-range discrete GPUs from previous generations. The B200's 50th percentile is a default value that carries no performance meaning.
