AMD releases an RDNA 3.0-based add-in board for 1080p gaming

Looks to expand the AIB market by introducing a new board at a $269 price point.

The new RX 7600 is an upgrade over the RDNA 2.0-based RX 6600 with an MSRP of only $269. At that price point, AMD hopes to get late adopters to upgrade, along with desktop gamers still utilizing iGPUs.

AMD introduced a new graphics add-in board for the entry level this week, the RX 7600, which is the first entry-level addition since the RX 6600 released in October 2021. The RX 7600 is based on the Navi 33 GPU. The Navi 33 is based on a 6nm process with 13,300 million transistors, with a modest 204mm2 die size. The RX 7600 features 2,048 streaming processors and 32 ray-tracing cores, both numbers represent a 14% upgrade over the RX 6600.

AMD is focusing this new board, which has 8MB of GDDR6, for 1080p gaming—AMD reports that 65% of gamers play at 1080p resolution. The MSRP for the RX 7600 is just $269, which is 18% less than the launch price of the RX 6600.

Features and specifications

The price tag for the RX 7600 may be low, but it offers many attractive features.

  • AMD RDNA 3 architecture—Featuring redesigned compute units with unified ray tracing and AI accelerators, along with second-generation AMD Infinity Cache technology, RDNA 3 delivers exceptional performance, visuals, and power efficiency.
  • Improved streaming quality and performance—Improved AMD encoders deliver enhanced visual quality when streaming and recording. AMD AI and content adaptive machine learning technology has also been integrated into the AMD Media Framework to enable crisper text when streaming at low bit rates and resolutions.
  • Ultra-high-definition encoding—An encode/decode media engine provides the ultimate performance, unlocking new multimedia experiences with full AV1 encode/decode support, wide color gamut, and high-dynamic range enhancements.
  • AMD Radiance Display Engine—Provides support for DisplayPort 2.1 on select models and HDMI 2.1a displays for ultra-high resolutions and high refresh rates for gaming and content creation workloads.
  • AMD FidelityFX Super Resolution (FSR)—Now available in more than 260 current and upcoming titles, AMD FSR upscaling technologies provide crisp, high-resolution image quality, while boosting frame rates in supported games.

The RX 7600 provides 21.75 FLOPS with a TDP of 165W.

AIB comparison.

We tested the RX 7600 vs. its RNDA 2.0 predecessor, the RX 6600.

Test bed

We tested the AIB on an Asus TUF Gaming Z790-Plus motherboard with an Intel 13th-gen Core i9-13900K CPU with 32MB of Corsair Vengeance RAM, running Windows 11 Pro. The SSD is a Samsung 960 Pro. We tested in two resolutions: 1080p and 1440p.

The above graph shows the performance boost provided by AMD’s FidelityFX Super Resolution. FidelityFX Super Resolution provided the RX 7600 with a 42% boost when running Cyberpunk 2077 at high preset in 1440p.

We ran the new 3DMark FSR feature test, which shows the FPS improvement with FSR enabled.

Test scores
The RX 7600 and RX 6600 FPS results for Guardians of the Galaxy.

The RX 7600 outperformed the RX 6600 by about 15% in FPS in Guardians of the Galaxy, with FidelityFX providing a massive performance boost for both AIBs when enabled.

Pmark calculations

JPR has been using its Pmark calculations to compare graphics boards for more than a decade. The Pmark scores factor overall performance of the add-in board and its price and power.

What do we think?
We were very impressed with the RX 7600. This is an entry-level-priced AIB targeted at 1080p gaming but still provides solid frame rates at 1440p. It clearly outperforms the RX 6600 yet is priced at 18% less at launch.

AMD is providing a solid value for casual gamers. At $269, it is their most economically priced add-in board since the release of the RX 5500 XT for $169 almost three years ago. The add-in board did not perform well when it came to ray-tracing benchmarks and gaming, but if you are looking for ray tracing, one is usually on the market for a performance segment or high-end graphics board. For $269, the RX 7600 would be very hard to beat.
