AMD Radeon RX 7800 XT/7700 XT assessment vs RTX 4070/4060 Ti

As we transfer into the mid-range sector of the GPU market, AMD’s newest – and final – RDNA 3-based desktop graphics playing cards signify yet one more golden alternative for AMD to seize some valuable market share from Nvidia. Put merely, the RTX 4060 Ti is the least compelling providing in your entire desktop 40-series line-up – it is the closest AMD goes to get to an open objective – whereas the RTX 4070’s worth proposition was controversial, being the most costly 70-series card Nvidia has ever made.

On the face of it, AMD’s new $499/£479 RX 7800 XT definitely gives a robust different to the RTX 4070. Primarily based on US pricing, it is $100 cheaper, you get undeniably stronger rasterisation efficiency and the 12 gigs of VRAM supplied by the Nvidia card will get a 4GB enhance on its new AMD competitor. That is AMD making life difficult for its competitors.

The $449/£429 RX 7700 XT? We’re reminded of launch pricing for the RX 7900 XT – it gives proportionately much less efficiency for the cash than its extra highly effective counterpart with 4GB much less framebuffer reminiscence too, this time with a extra impactful drop from a 16GB to 12GB allocation. It is completely baffling, because the RTX 4060 Ti 8GB was a turkey, and within the meantime, value cuts on the 16GB mannequin add additional strain to the 7700 XT. It simply does not fairly make sense.

As we famous in our protection of their official announcement, each of the brand new AMD graphics playing cards are based mostly round a singular Navi 32 GPU, with the RX 7800 XT being the fully-enabled 60CU mannequin and the RX 7700 XT utilizing a cut-back 54CU specification. Which means the 2 playing cards ought to supply comparatively comparable efficiency in comparison with the last-gen RX 6800 XT and 6700 XT, which have 72CUs and 40CUs respectively.

Different spec factors are additionally shut between the 2 playing cards, with an 18W TDP and 1.5Gbps reminiscence pace benefit for the 7800 XT, partially made up for a rated 114MHz enhance clock benefit for the 7700 XT.

Regardless of sharing a standard Navi 32 GPU, the 2 playing cards we examined for this assessment are available in barely completely different clothes. The RX 7800 XT is AMD’s reference design, a curvy dual-slot mannequin with two followers and two eight-pin energy inputs; whereas the RX 7700 XT we acquired is a Sapphire Pulse mannequin with a boxier look however matching fan depend and I/O. With no particular 12VHPWR connector, these can be utilized with a variety of energy provides sans adapter.

Energy evaluation, utilizing Nvidia’s PCAT interposer {hardware} sitting between the graphics card and its energy sources (PCIe slot and auxiliary inputs), reveals higher energy effectivity for the Ada Lovelace playing cards by way of Joules per body – by a comparatively advantageous margin in non-RT titles and by a way more vital distinction in RT workloads the place AMD’s {hardware} is on the again foot.

For the RX 7800 XT, for instance, we’re 5.1 and 5.4 Joules per body respectively in Dying Gentle 2 and Management with RT enabled, versus simply 1.9 and 1.1 Joules per body respectively in Forza Horizon 5 and Hitman 3 with RT disabled. The RTX 4070, against this, requires solely ~3.5Jpf within the RT workloads and 1.0-1.4Jpf within the non-RT checks. That works out because the RX 7800 XT drawing round 50 % extra Joules per body within the RT checks, versus a narrower 25 % enhance in non-RT.

There is a comparable margin for the RX 7700 XT versus the RTX 4060 Ti, with round a 55 % enhance in energy consumption per body on common in our two RT checks, versus a few 20 % common enhance in non-RT workloads. After all, completely different video games and scenes lead to completely different numbers, nevertheless it’s clear that Nvidia’s glorious effectivity with its mid-range 40-series playing cards stays out of attain for AMD’s RDNA 3 opponents.

With the preliminaries out of the best way, it is time to get into the benchmarks correct. As typical, we’re utilizing a high-end rig that pairs a Core i9 13900K with 6000MT/s GSkill DDR5 and an Asus ROG Maximus Hero Z690 motherboard, minimising CPU bottlenecking to indicate GPU variations extra clearly.
