At Gamescom 2023, AMD officially announced the much-anticipated Radeon RX 7800 XT and RX 7700 XT, filling a significant gap in its RDNA 3 GPU lineup. These graphics cards are designed to deliver a solid 1440p gaming experience at 60+ FPS (even in the most demanding AAA titles) while also competing directly with Nvidia’s GeForce RTX 4070 and RTX 4060 Ti.

To better understand the capabilities of AMD’s current-gen GPU architecture, here’s a comprehensive breakdown of all the relevant details surrounding the RX 7800 XT and RX 7700 XT.

RX 7800 XT vs. RX 7700 XT: Specifications and Overview

For starters, both the Radeon RX 7800 XT and RX 7700 XT are built around AMD’s brand-new Navi 32 GPU die, which adopts a chiplet-based design to reduce manufacturing costs and facilitate production. Like before, the central section of this GPU features a relatively smaller GCD (Graphics Compute Die) than Navi 31 (fabricated on TSMC’s N5 process), flanked by four MCDs (Memory Complex Die) utilizing an older yet efficient N6 technology.

Consequently, AMD’s Radeon RX 7800 XT and RX 7700 XT share a similar configuration with the flagship RX 7900 Series (we’ve previously comparedRX 7900 XTX vs. RX 7900 XT ), as opposed to thebudget-oriented RX 7600 , which employs a monolithic Navi 33 die. On paper, the RX 7800 XT benefits from a fully unlocked Navi 32 GPU, incorporating 60 CUs (or 3,840 Stream Processors), 120 AI accelerators, 64MB of Infinity Cache, and 16GB of GDDR6 memory (clocked at 19.5Gbps) over a 256-bit memory bus.

Meanwhile, the RX 7700 XT uses a cut-down version of the same GPU die with three active MCDs, housing 54 CUs (or 3,456 cores), 108 AI accelerators, 48MB of Infinity Cache, and 12GB of GDDR6 memory (on a narrower 192-bit memory bus) clocked at around 18Gbps. Owing to these adjustments, the RX 7700 XT prioritizes slightly higher clock speeds than the RX 7800 XT, registering an average Game Clock of 2,171MHz and a maximum Boost Clock of 2,544MHz.

Regarding power consumption, both GPUs from AMD remain comparable across the board, with the RX 7700 XT officially rated at 245W, whilst the RX 7800 XT exhibits a marginal increase in its TBP of about 18W. Despite the RDNA 3 microarchitecture’s generational improvement, Team Red’s upcoming duo still suffers from an inferior power profile compared to Nvidia’s AD104 and AD106 silicon.

Aside from the differences in compute performance, memory subsystem, power consumption, and core frequencies, the Radeon RX 7800 XT and RX 7700 XT take advantage of all the latest and greatest features associated with the RDNA 3 microarchitecture. Both variants offer native support for the newDisplayPort 2.1 standard , AV1 encoding and decoding, along with other proprietary technologies from Team Red, including Radeon Super Resolution, Radeon Anti-Lag, and many more.

Moving on to the connectivity front, AMD’s port configuration for the RX 7800 XT and RX 7700 XT misses out on the highly convenient USB-C Virtual Link connector, as seen previously in the RX 7900 Series. While providing a maximum of four video outputs, the upcoming models will include three DisplayPort 2.1 UHBR13.5 ports (at data rates up to 54Gbps) alongside a single HDMI 2.1 connector.

The specifications alone show that the RX 7800 XT is a logical replacement for the RX 6800 rather than its direct predecessor—the RX 6800 XT. Given how closely the CU count aligns between both GPUs, a straightforward contender for the RX 6800 XT happens to be AMD’s China-exclusive Radeon RX 7900 GRE (Golden Rabbit Edition), which packs a total of 80 compute units and is currently priced at $649.

On the contrary, the RX 7700 XT presents a compelling upgrade path from the previous-gen RX 6700 XT and its mid-gen refresh—the RX 6750 XT—albeit at a $100 price premium. Nevertheless, it remains to be seen whether AMD has truly delivered a noteworthy generational uplift or inadvertently launched a costly sidegrade like Nvidia’s much-maligned GeForce RTX 4060 Ti.

RX 7800 XT vs. RX 7700 XT: Gaming Performance

According to AMD’s internal benchmarks, the Radeon RX 7800 XT engages in a back-and-forth battle with Nvidia’s $600 RTX 4070, whereas the RX 7700 XT stands favorably against the $500 RTX 4060 Ti 16GB variant. More importantly, both GPUs demonstrate the ability to surpass the 60 FPS threshold at 1440p, “Ultra” settings in a range of recent AAA titles.

Across the 19-game configuration sample, the RX 7700 XT outperforms Nvidia’s GeForce RTX 4060 Ti 16GB by about 12% on average. Interestingly, AMD’s scaled-down Navi 32 GPU secures a 17% lead in rasterization performance while exhibiting a mere 4% deficit in certain games that implement advanced ray tracing effects.

Furthermore, AMD’s performance figures for the RX 7800 XT put it in a formidable position against the RTX 4070, showcasing a 9% advantage in rasterization and a 6% deficit in select RT titles. Although the average gain isn’t as impressive as seen in the previous slide, the RX 7800 XT undercuts Nvidia’s upper mid-range offering by around $100.

RX 7800 XT vs. RX 7700 XT: Pricing and Availability

At an MSRP of $499, AMD’s Radeon RX 7800 XT represents a better price-to-performance ratio than the cut-down Navi 32 variant on multiple occasions. If the performance numbers for both GPUs hold true, the RX 7700 XT, at a starting price of $449, could face some potential challenges in its own lineup.

Regardless, AMD’s mid-tier graphics cards are set to hit the market on September 6, 2023. To sweeten the deal further, Team Red will also include a free copy of Bethesda’s long-awaited space RPG, Starfield, with the purchase of these GPUs.

While the Radeon RX 7800 XT comes in an AMD reference dual-fan, dual-slot design, alongside custom variants, the RX 7700 XT will only be made available through AIB partners like ASRock, ASUS, Biostar, Gigabyte, PowerColor, Sapphire, Vastarmor, XFX, and Yeston.

AMD’s Next-Gen 1440p Gaming GPUs Unveiled

From what has been revealed, AMD’s marketing strategy for this launch involves pitting the Radeon RX 7800 XT and RX 7700 XT against older yet capable 1440p cards. Considering the recent adoption of QHD displays, both GPUs should be able to offer a stellar gaming experience, with enough headroom to drive graphically demanding titles at 4K.

Ultimately, the success of these sub-$500 graphics cards will depend largely on their real-world performance, feature set, and overall, given that this market segment is highly competitive.
