AMD Radeon 840M vs NVIDIA RTX 4500 Ada Generation Comparison

AMD Radeon 840M is an integrated graphics processor built for mobile platforms, while the NVIDIA RTX 4500 Ada Generation is a dedicated workstation-class add-in board. The database places the AMD part at the 50th percentile of all GPUs, while the NVIDIA card sits at the 97th percentile. The RTX 4500 Ada Generation has an average benchmark score of 166,094 across its recorded tests, whereas the Radeon 840M has no recorded benchmark scores in the database, making direct numeric comparison impossible from the available data.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries comparing the AMD Radeon 840M and the NVIDIA RTX 4500 Ada Generation directly. The Radeon 840M has an empty benchmarks array, meaning no Geekbench OpenCL or Vulkan results are recorded for it. The RTX 4500 Ada Generation, on the other hand, has two recorded benchmark scores: 160,786 in Geekbench OpenCL and 171,401 in Geekbench Vulkan. These two results produce an average benchmark score of 166,094 for the NVIDIA card.

Because the AMD part lacks any benchmark entries, the data offers no direct wins for the Radeon 840M. The NVIDIA RTX 4500 Ada Generation, by contrast, shows a strong position relative to its nearest rivals in the database. It sits 0.5% above the NVIDIA RTX A5500, which has an average score of 165,217. It is 0.7% ahead of the AMD Radeon PRO W7800, which averages 164,894. Against the AMD Radeon Pro W6900X, the RTX 4500 Ada Generation trails slightly, with that rival posting an average score of 168,574, a 1.5% advantage over the RTX 4500. The NVIDIA A100 PCIe 40 GB scores 162,504, putting the RTX 4500 Ada Generation 2.2% ahead of it.

The recorded data shows the RTX 4500 Ada Generation delivers a higher Geekbench Vulkan score than its OpenCL score, 171,401 versus 160,786, a difference of roughly 6.6% within its own results. No such comparison can be made for the Radeon 840M because no scores exist.

Where Each One Wins

The NVIDIA RTX 4500 Ada Generation wins every measurable category in the database. Its benchmark scores place it in the 97th percentile of all GPUs, while the AMD Radeon 840M sits at the 50th percentile. The RTX 4500 Ada Generation also wins on raw compute metrics. Its FP32 throughput is 39.63 TFLOPS, compared to 1,484.8 GFLOPS for the Radeon 840M. The NVIDIA card delivers 206.4 GPixel/s pixel rate and 619.2 GTexel/s texture rate, while the AMD part reaches 23.20 GPixel/s and 46.40 GTexel/s. The RTX 4500 Ada Generation uses 7,680 shading units, 240 texture mapping units, and 80 render output units, whereas the Radeon 840M uses 256 shading units, 16 TMUs, and 8 ROPs.

The AMD Radeon 840M has no recorded benchmark wins. Its only advantage in the database is its power draw. The Radeon 840M is rated at 15 W TDP, while the RTX 4500 Ada Generation is rated at 210 W. The AMD part also has a higher boost clock in the database, 2900 MHz versus 2580 MHz for the NVIDIA card, though this does not translate into higher recorded performance. The Radeon 840M uses system shared memory, which means its bandwidth is system dependent, while the RTX 4500 Ada Generation has a fixed 432.0 GB/s memory bandwidth from its 24 GB GDDR6 memory on a 192-bit bus.
