This article covers ASRock グラフィックボード AMD Radeon RX6600 GDDR6 8GB 搭載モデル 【国内正規代理店品】 RX6600 CLD 8G.

Overview

The ASRock RX6600 CLD 8G is a mid-range graphics card built around AMD's Radeon RX 6600 GPU. It packs 8GB of GDDR6 memory on a 128-bit bus, with a boost clock of 2491 MHz. This card targets 1080p gaming, delivering high frame rates in popular competitive titles and solid performance in modern AAA games at medium-to-high settings. With a TDP of just 132W and a single 8-pin power connector, it's also an excellent choice for builders with modest power supplies or compact cases.
ASRock's dual-fan cooling solution keeps temperatures in check while maintaining low noise levels, and the card includes handy features like 0dB fan stop at idle. The RX6600 CLD 8G is sold as a Japanese authorized retail version, backed by a 2-year manufacturer warranty.

Compatibility Guide

The RX6600 uses a PCI Express 4.0 x16 interface, which works fine in PCIe 3.0 slots with minimal performance impact. Memory type is GDDR6; 8GB is sufficient for most current games at 1080p and even 1440p with moderate textures. Power is drawn through a single 8-pin PCIe connector; a 500W or higher PSU is recommended (550W for extra headroom).
The card measures approximately 269mm in length and occupies two expansion slots. It fits most mid-tower and full-tower cases, but check space in small-form-factor enclosures. Video outputs include three DisplayPort 1.4 ports and one HDMI 2.1 port, allowing flexible monitor setups and easy connection to modern TVs.

Product Info

Launched in late 2021, the ASRock RX6600 CLD 8G sits in the mid-range segment. Its typical street price in Japan is around ¥48,000. The card competes directly with NVIDIA's GeForce RTX 3050 and RTX 3060. With a TDP of 132W and dual fans, it offers a strong price-to-performance ratio for 1080p gamers. The warranty is 2 years when purchased via authorized channels.

Best Use Cases

① 1080p 144Hz Gaming – Ideal for eSports fans (VALORANT, Apex, Overwatch 2) who want consistently high frame rates. The RX 6600 can push well over 144 fps in lighter titles and stays above 60 fps in AAA games. Avoid if you need heavy ray tracing or 4K gaming.
② First-Time PC Builder – Low power draw and simple single 8-pin power connector simplify installation. The 2-year warranty provides peace of mind. Not recommended for users who want RGB lighting on the card itself (consider ASRock's Phantom Gaming series instead).
③ Media Center or Secondary PC – Low heat output (132W TDP) and support for hardware decode/encode (including HEVC, AVC, and AV1 decode) make it a good fit for HTPC builds. The HDMI 2.1 port handles 4K 60 Hz output easily. Not suitable for heavy video editing or 3D rendering – the RTX 3060 with 12GB would be better for those workloads.

Things to Consider

Ray tracing performance on the RX 6600 is modest; if ray tracing matters, an NVIDIA RTX 3060 at a similar price may be more appropriate. The 8GB VRAM is adequate today but could become a bottleneck in future titles if high-resolution textures become standard. For creative workloads, the RTX 3060's 12GB VRAM gives it an edge.
Compared to similarly priced competitors, the RX 6600 generally matches or beats the RTX 3050 in rasterization and is often cheaper than the RTX 3060 while offering competitive frame rates. However, driver overhead in CPU-limited situations can be higher with AMD, though this is rarely noticeable in real-world gaming.

FAQ

Q: Can the RX 6600 handle 1440p gaming?
A: Yes, but expect to reduce settings to medium for 60 fps in demanding titles. For high refresh rate 1440p, consider the RX 6700 series or higher.
Q: Does this card have a fan-stop mode?
A: Yes. ASRock's dual-fan cooler supports 0dB mode, where fans stop entirely when the GPU is below a certain temperature, ensuring silent operation during light tasks.
Q: How does this compare to the ASRock RX 6600 Phantom Gaming model?
A: The Phantom Gaming model features a slightly higher boost clock and more aggressive cooling, but the core performance difference is minimal. The CLD model is often more affordable and still has excellent cooling for the price.
