Analysis: AMD Radeon HD 7950 vs NVIDIA P104-100

Head-to-Head Benchmarks

The benchmark database provides no direct head-to-head test results between the AMD Radeon HD 7950 and the NVIDIA P104-100. Instead, the comparison must be constructed from their individual average benchmark scores and the percentile rankings that place them within the broader GPU landscape. The AMD Radeon HD 7950 posts an average benchmark score of 33,951, while the NVIDIA P104-100 posts a slightly lower average of 32,982. That gap of 969 points works out to roughly 2.9% in favor of the older AMD card, a margin that is small enough to be considered a statistical tie in most workloads, yet it is consistent across the available data.

Looking at the percentile rankings, the AMD Radeon HD 7950 sits at the 78th percentile of all GPUs, while the NVIDIA P104-100 sits at the 77th percentile. This one-percentile difference reinforces the narrowness of the overall performance gap. The AMD card’s single benchmark entry is a Geekbench Metal score of 33,951, which is its only datapoint and also its average. The NVIDIA card, by contrast, has three benchmark entries: a 3DMark Steel Nomad DX12 score of 1,413, a Geekbench OpenCL score of 52,368, and a Geekbench Vulkan score of 45,165. The fact that the NVIDIA card’s average is pulled down to 32,982 despite those strong OpenCL and Vulkan numbers suggests the 3DMark DX12 result is significantly lower, dragging the mean below what the other two tests would imply.

Examining the nearest rivals for each card provides additional context. The AMD Radeon HD 7950’s closest competitor in the database is the AMD Radeon RX 480, which scores 33,997, a delta of -0.1% relative to the HD 7950. That means the HD 7950 is effectively level with the RX 480, differing by a mere 46 points. The next nearest rivals are the AMD Radeon RX 7700S at 33,849 (delta +0.3%), the AMD Radeon RX 560 XT at 34,133 (delta -0.5%), and the NVIDIA RTX A2000 12 GB at 34,154 (delta -0.6%). For the NVIDIA P104-100, the nearest rival is the NVIDIA T600 Mobile at 32,849 (delta +0.4%), followed by the NVIDIA T550 Mobile at 33,161 (delta -0.5%), the NVIDIA GeForce RTX 3050 Mobile at 33,170 (delta -0.6%), and the AMD Radeon Pro 570 at 33,207 (delta -0.7%). These deltas show that both cards sit in a dense cluster of GPUs where a few dozen points separate one model from the next.

The strongest individual benchmark win for the NVIDIA P104-100 is its Geekbench Vulkan score of 45,165, which is substantially higher than the AMD card’s Geekbench Metal score of 33,951. However, those are different APIs, so a direct comparison is not apples-to-apples. The NVIDIA card’s Geekbench OpenCL score of 52,368 is even more impressive in absolute terms, but again, the AMD card has no OpenCL entry to compare against. The only shared test type in the database is Geekbench, but the AMD card uses Metal while the NVIDIA card uses OpenCL and Vulkan, so no identical test links the two. What the data does show is that the NVIDIA P104-100 excels in compute-oriented APIs, while the AMD Radeon HD 7950 holds its own in the Metal test that is reported for it.

The Verdict

Based strictly on the average benchmark scores, the AMD Radeon HD 7950 is the marginally faster card overall, with an average score of 33,951 versus 32,982 for the NVIDIA P104-100. That 2.9% advantage is real but small, and the percentile rankings agree, with the AMD card at the 78th percentile and the NVIDIA card at the 77th percentile. For a user who cares about a single aggregate number, the AMD Radeon HD 7950 comes out ahead, but the margin is thin enough that real-world differences would likely be imperceptible in most tasks.

The NVIDIA P104-100, however, presents a different profile when individual tests are considered. Its Geekbench OpenCL score of 52,368 is roughly 54% higher than the AMD card’s Geekbench Metal score of 33,951, and its Vulkan score of 45,165 is about 33% higher. These are different APIs, so the comparison is not direct, but the magnitude of the difference suggests that in compute-heavy workloads using OpenCL or Vulkan, the NVIDIA card has a clear edge. The 3DMark Steel Nomad DX12 score of 1,413 is the NVIDIA card’s weakest result, and it is this number that drags its average down.

For a user who needs a general-purpose GPU with balanced performance across APIs, the AMD Radeon HD 7950 is the safer choice based on the average score. For a user who knows their workloads rely on OpenCL or Vulkan compute, the NVIDIA P104-100 is the stronger pick, despite its lower average. The NVIDIA card’s lack of display outputs is a critical caveat, as it cannot drive a monitor on its own. The AMD card, by contrast, offers a full set of display outputs including 1x DVI, 1x HDMI 1.4a, and 2x mini-DisplayPort 1.2. This makes the AMD card the only viable option for a desktop user who wants to see output on a screen.

Where Each One Wins

The AMD Radeon HD 7950 wins on overall average benchmark score, posting 33,951 against the NVIDIA P104-100’s 32,982. It also wins on percentile ranking, sitting at the 78th percentile versus the 77th percentile. In terms of nearest rivals, the AMD card’s closest competitor is the AMD Radeon RX 480 at 33,997, which is only 46 points higher, while the NVIDIA card’s closest competitor is the NVIDIA T600 Mobile at 32,849, which is 133 points lower. This indicates that the AMD card is placed in a slightly higher performance tier among its peers.

The NVIDIA P104-100 wins decisively in raw compute-oriented benchmarks. Its Geekbench OpenCL score of 52,368 is the highest single score recorded for either card, and its Geekbench Vulkan score of 45,165 is also well above the AMD card’s Metal result. In terms of memory bandwidth, the NVIDIA card offers 320.3 GB/s versus 240.0 GB/s for the AMD card, a 33% advantage that likely contributes to its compute performance. The NVIDIA card also has a higher pixel rate at 110.9 GPixel/s versus 25.60 GPixel/s, and a higher texture rate at 208.0 GTexel/s versus 89.60 GTexel/s. These are not benchmark scores, but they are specification-level indicators that the NVIDIA card is built for throughput.

The AMD Radeon HD 7950 wins on compatibility and usability. It has display outputs, a PCIe 3.0 x16 interface, and a 550 W suggested PSU. The NVIDIA P104-100 has no display outputs and uses a PCIe 1.0 x4 interface, which is a severe bottleneck for data transfer even if the card’s compute capabilities are strong. The AMD card also supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, while the NVIDIA card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card’s newer API versions are a point in its favor, but the lack of display outputs is a dealbreaker for most users.
