AMD Radeon RX 6600S vs NVIDIA TITAN V CEO Edition Comparison

AMD Radeon RX 6600S vs NVIDIA TITAN V CEO Edition is a matchup of two very different design philosophies, one a low-power mobile chip and the other a desktop compute powerhouse. The recorded head-to-head data shows the NVIDIA TITAN V CEO Edition winning both benchmark comparisons, but the AMD Radeon RX 6600S holds its own as a capable mobile graphics solution. The TITAN V CEO Edition leads in the two shared tests, while the RX 6600S brings a much broader benchmark footprint, with over 8 recorded tests versus just 2 for the NVIDIA card.

Head-to-Head Benchmarks

The direct comparison data is limited to two PassMark tests, and the NVIDIA TITAN V CEO Edition wins both. In the PassMark G2D test, which measures 2D graphics performance, the TITAN V CEO Edition scores 1086, while the AMD Radeon RX 6600S scores 647. This represents a 40.4% deficit for the AMD card, a significant gap in that specific workload. The NVIDIA card's advantage here likely stems from its desktop-oriented design and different rendering path, though the exact architectural reasons are not in the data.

The PassMark G3D test, which focuses on 3D graphics performance, shows a closer but still clear win for the NVIDIA card. The TITAN V CEO Edition scores 16988, while the RX 6600S scores 12649. The delta is 25.5%, meaning the NVIDIA card outperforms the AMD chip by roughly a quarter in this test. This is a substantial margin, and it aligns with the raw compute figures in the database. The TITAN V CEO Edition delivers 14.90 TFLOPS of FP32 performance versus 7.168 TFLOPS for the RX 6600S, so the 3D benchmark gap is proportionally smaller than the theoretical peak difference, suggesting the AMD card scales reasonably well despite lower absolute throughput.

Looking at the broader benchmark data, the RX 6600S has a much richer test history. It records scores across Geekbench OpenCL (66435), PassMark DirectX 10 (81), DirectX 11 (105), DirectX 12 (56), DirectX 9 (176), G2D (647), G3D (12649), and GPU Compute (4879). The TITAN V CEO Edition only has G2D and G3D scores in the database. This means the head-to-head is incomplete, but the available data still offers a clear verdict: the NVIDIA card is faster in both measured areas. The RX 6600S averages 10629 across its benchmark suite, while the TITAN V CEO Edition averages 9037, but this average is skewed by the different test sets. The average benchmark score for the AMD card is higher because it includes Geekbench OpenCL, which heavily favors it, whereas the NVIDIA card's average only reflects its two PassMark results.

The Verdict

Based strictly on the recorded measurements, the NVIDIA TITAN V CEO Edition is the faster graphics processor. It wins both head-to-head tests, with the G3D result being particularly decisive at 25.5% ahead. The data shows the TITAN V CEO Edition is the better choice for users prioritizing raw 3D graphics performance and 2D rendering speed. Its 32 GB of HBM2 memory and 4096-bit bus width provide 868.4 GB/s of bandwidth, compared to the RX 6600S's 4 GB GDDR6 on a 128-bit bus with 224.0 GB/s. That memory bandwidth difference alone is massive, at roughly 3.9 times the AMD card's capacity, and it directly explains the G3D gap.

However, the AMD Radeon RX 6600S is not without merit. Its 80 W TDP versus the 250 W TDP of the TITAN V CEO Edition means it operates in a completely different power envelope, though power consumption figures are not part of the benchmark scores. The RX 6600S also supports PCIe 4.0 x8, while the NVIDIA card uses PCIe 3.0 x16, and the AMD card's DirectX 12 Ultimate support (12_2) exceeds the NVIDIA card's DirectX 12 (12_1) level. For a mobile or compact system, the RX 6600S is the only viable option given its IGP slot width and portable-device-dependent display outputs. The TITAN V CEO Edition is a dual-slot desktop card requiring a 600 W suggested PSU.

Where Each One Wins

The NVIDIA TITAN V CEO Edition wins in 3D graphics performance and 2D rendering, as shown by the head-to-head data. The PassMark G3D score of 16988 places it 25.5% ahead of the RX 6600S in that test. The G2D score of 1086 is 40.4% ahead of the AMD card, indicating a wide margin in 2D workloads. The TITAN V CEO Edition also has a massive memory advantage, with 32 GB of HBM2 versus 4 GB of GDDR6, and a bandwidth of 868.4 GB/s versus 224.0 GB/s. This makes it suited for compute-heavy tasks that rely on memory throughput, such as large dataset processing or high-resolution texture workloads, though specific application tests are not in the database.

The AMD Radeon RX 6600S wins in efficiency and feature set, based on the available data. Its 7 nm process node versus the NVIDIA card's 12 nm node, and its transistor density of 46.7M per mm² versus 25.9M per mm², indicate a more modern and compact design. The RX 6600S also has dedicated ray tracing cores (28 of them), while the TITAN V CEO Edition has none listed. Additionally, the AMD card supports DirectX 12 Ultimate, while the NVIDIA card only supports DirectX 12 (12_1). The RX 6600S's 80 W TDP makes it suitable for thin-and-light laptops, as it requires no power connectors and is an IGP form factor. The NVIDIA card requires both a 6-pin and an 8-pin power connector, plus a 600 W suggested PSU.
