AMD Radeon 6700 XT Assessment: A Nice GPU at a Difficult Worth

Previous this week, we tested the Radeon RX 6700 XT’s IPC and tool intake enhancements in opposition to its predecessor, the RDA-based 5700 XT. Our checks published that the Radeon 6700 XT is considerably extra power-efficient than the Radeon 5700 XT when each playing cards are measured at 1.85GHz. Now we’re taking a fuller have a look at the RX 6700 XT as in comparison with the RTX 3070, in addition to Nvidia’s previous-generation RTX 2080 and the 5700 XT.

The 6700 XT is in line with the Navi 22 GPU core. Its efficiency in opposition to the 5700 XT has been of explicit hobby, because it’s a near-identical alternative for that GPU so far as core useful resource allocation. Our checks previous this week confirmed that RDNA2 is solely relatively sooner than RDNA when measured clock-for-clock, however that AMD’s L3 cache and smaller reminiscence bus have paid massive dividends in chronic potency. Right here’s how the 6700 XT stacks up in opposition to the 5700 XT, in addition to the contest from Group Inexperienced:

The connection between the RTX 2080 and RTX 3070 (most commonly) mirrors the connection between the RX 5700 XT and 6700 XT. The RTX 3070 has way more cores than the RTX 2080, and its tensor core and ray tracing efficiency are increased total. However the two GPUs proportion the similar choice of texture mapping gadgets, render outputs, and ray tracing cores. Reminiscence bandwidth on each GPUs is similar at 448GB/s, they run at just about similar clock speeds, and so they each have 8GB body buffers.

AMD’s $479 positioning at the RX 6700 XT seems beautiful positive to start with look. GPUs from other households can’t be without delay in comparison at the foundation of core counts, ROPs, or TMUs, however extra of this stuff nonetheless has a tendency to be higher, and the RTX 3070 packs extra of the whole thing the RX 6700 XT has to supply (aside from VRAM and clock). The bottom clock of 2325MHz at the 6700 XT is at least 1.54x sooner than the bottom clock at the RTX 3070, and the 6700 XT provides 12GB of RAM, in comparison with simply 8GB on different playing cards. We’ll run some checks lately geared toward checking out how a lot this extra VRAM issues.

Our RTX 3070 GPU is an MSI Gaming X Trio — we reviewed this card remaining 12 months should you’re searching for extra model-specific knowledge.

Check Setup and Configuration

We’re switching to a brand new graphing engine right here at ExtremeTech, so tell us what you call to mind the brand new design whilst you test it out under. The graph under displays our effects for 4 video playing cards. You’ll choose or de-select which playing cards you need to peer via clicking at the colour buttons subsequent to each and every card.

Recreation effects had been blended for the 3 Overall Battle: Troy benchmark maps (Combat, Marketing campaign, and Siege), resulting in the “Mixed” rating. In a similar fashion, effects from Hitman 2’s Miami and Mumbai maps had been averaged to provide a unmarried consequence. Gaps between the playing cards in those maps had been proportional and this averaging does no longer distort the total comparability between the 3 playing cards in the ones titles.

This presentation approach prevents us from giving per-game element settings within the graph frame, so we’ll duvet the ones under:

Ashes of the Singularity: Escalation: Loopy Element, DX12.

Murderer’s Creed: Origins: Extremely Element, DX11.

Borderlands 3
: Extremely element, DX12

Deus Ex: Mankind Divided
: Very Prime Element, 4x MSAA, DX12

A long way Cry 5
: Extremely Element, Prime Element Textures enabled, DX11.

Godfall (RT-only): We solely examined Godfall with ray tracing enabled, in Epic Element. Grats to the Godfall builders for arising with a reputable title for a preset above “Extremely” that isn’t “Excessive.”

Hitman 2 Mixed
: Extremely element, however efficiency measured via “GPU” body price reported by the use of the benchmarking device. This maintains continuity with the older Hitman effects, that have been reported the similar method. Miami and Mumbai take a look at effects blended. Examined in DX12.

Metro Exodus
: Examined at Excessive Element, with Hairworks and Complex Physics disabled. Excessive Element turns on 2xSSAA, successfully rendering the sport at 4K, 5K, and 8K when checking out 1080p, 1440p, and 4K. Examined in DX12.

Metro Exodus (RT): Extremely Element, with Extremely ray tracing enabled. The one distinction between Extremely and Excessive Element in Metro Exodus is that Excessive permits 2x SSAA, successfully rendering the sport at double the answer. Hairworks and Complex physics disabled.

Shadow of the Tomb Raider
: Examined at Prime Element, with SMAATx2 enabled. Makes use of DX12.

Extraordinary Brigade
: Extremely Element, Vulkan.

Overall Battle: Troy Mixed
: Extremely element, DX12.

Overall Battle: Warhammer II
: Extremely element, Skaven benchmark, DX12.

Watch Canines Legion (RT-Most effective): Examined on Extremely element with extremely ray tracing enabled and disabled.

Our take a look at settings are competitive and put a heavy load on GPUs, particularly Metro Exodus and Deus Ex: Mankind Divided. Checking out those GPUs at non-playable speeds can lend a hand disclose variations within the underlying architectures.

All video games had been examined the use of an AMD Ryzen 9 5900X on an MSI X570 Godlike provided with 32GB of DDR4-3200 RAM. AMD’s Ryzen 6700 XT release driving force was once used to check each the 5700 XT and 6700 XT. AMD’s release Radeon RX 6700 XT driving force was once used for all AMD GPUs and Nvidia’s 461.92 driving force treated NV playing cards. Good Get admission to Reminiscence / Resizable BAR was once enabled for the Radeon 6700 XT however disabled for the 5700 XT, RTX 2080, and RTX 3070.

Efficiency Effects and Research

We’ll speak about rasterization effects first, then transfer over and chat on ray tracing.

In 1080p, in combination, the RTX 2080 is 15 p.c sooner than the RX 5700 XT and the 6700 XT is 7 p.c sooner than the RTX 2080. The RTX 3070, in flip, is 11 p.c sooner than the RX 6700 XT. AMD refers back to the 6700 XT as an fanatic’s 1440p GPU and the knowledge as soon as once more bears out this positioning — in 1440p the 6700 XT widens its lead over Turing to fourteen p.c. The RTX 3070 remains to be sooner total, however via simply 6 p.c. The gaps widen once more in 4K, with the RTX 2080 successful over 5700 XT via 20 p.c, 6700 XT as soon as once more 1.07x sooner than the RTX 2080, and the RTX 3070 beating the 6700 XT via 1.16x.

There are some benchmarks the place the 6700 XT pulls forward of the 5700 XT via a larger-than-expected margin in 1440p, together with Ashes of the Singularity: Escalation, Shadows of the Tomb Raider, Extraordinary Brigade, and Overall Battle Troy, in particular TWT. Overall Battle Troy is an engaging instance of a sport that responds extraordinarily smartly to AMD’s L3 cache in a single particular answer. Efficiency craters in 4K, however it craters for each AMD GPUs.

Our ray tracing effects glance a lot as we’d be expecting, however the 4K knowledge, particularly, is price your consideration:

There’s some proof to signify that Nvidia’s choice to equip the RTX 3070 with simply 8GB of VRAM in point of fact can be a proscribing consider video games going ahead. There’s proof of this in each Godfall and Watch Canines Legion, in particular WDL.

1080p and 1440p display equivalent patterns of efficiency between the 3 playing cards. Extremely element is very laborious on each the RTX 2080 and the 6700 XT, without or with ray tracing enabled. After we hit 4K, alternatively, issues exchange. Each the RTX 2080 and 3080 fall off a cliff in Godfall, the place the RX 6700 XT outperforms them via over 3x.

In Watch Canines Legion, the RTX 3070 is at least 2.91x sooner than the 6700 XT in 1440p, however loses to it in 4K. Whilst not one of the GPUs turns in a playable body price, the wholesale cave in of the Nvidia playing cards at excessive answer is indicative of 1 factor: an inadequate VRAM buffer.

That is relating to when it comes to the RTX 3070, which in point of fact must have sufficient horsepower to step as much as 4K with ray tracing enabled, however can’t achieve this in titles you’ll be able to already purchase lately. Whilst total ray tracing efficiency at the RTX 3070 is increased than the 6700 XT in each 1080p and 1440p (and via a vital margin), the RX 6700 XT makes a potent argument in want of its personal 12GB VRAM buffer at 4K and ratings a couple of issues within the procedure.

Energy Intake

Energy intake was once measured in Metro Exodus and Metro Closing Gentle Redux at the 3rd loop of a three-benchmark run. I threw Closing Gentle Redux again into the combination once I spotted Exodus stressed out the 5700 XT a little in a different way. I’ve additionally proven the low-power consequence from working the Radeon 6700 XT at 1.85GHz (to check the 5700 XT). We mentioned those effects extra in our IPC comparability previous this week.

There’s a a lot more effective chip hiding throughout the 6700 XT. Matched clock for clock in opposition to the 5700 XT, the 6700 XT is rather chronic effective. At 1.85GHz, it’s in reality extra effective when it comes to chronic intake in keeping with body drawn than the RTX 3070. Cranking up the clock to compete with Nvidia reduces the 6700 XT’s potency, and the RTX 3070 is extra effective when each GPUs are run at complete velocity.

When compared with the 5700 XT, the 6700 XT provides a 1.20x build up in efficiency in Exodus at a slight build up in chronic intake. It is a bit worse than its 1440p efficiency total, the place it provides 1.34x higher efficiency than the 5700 XT. It is a very vital stage of uplift for a GPU that’s a near-mirror of its predecessor, and it speaks to AMD’s paintings optimizing RDNA2’s clock scheme and total potency.

Right here’s yet another tidbit. The Radeon VII (no longer proven) hits round 1.8GHz most and attracts about 402W in Metro Closing Gentle. The 5700 XT pulls about 350W on this take a look at at a 1.85GHz clock, whilst the 6700 XT attracts 267W at 1.85GHz. Efficiency between all 3 GPUs is identical at this clock, with the 6700 XT main modestly. This implies AMD has drawn down its 7nm chronic intake from 402W on the release of Radeon VII to a hypothetical 267W lately, a minimum of on this particular take a look at. That knowledge level doesn’t have any direct touching on our assessment, because the Radeon 6700 XT isn’t a 1.85GHz card, however it is helping illustrate the lengthy arc of AMD’s RDNA2 potency good points.


The 6700 XT has some cast sturdy issues. AMD’s efforts to deliver some Ryzen DNA to RDNA2 have obviously paid off. There’s no signal of untoward reminiscence bandwidth power at the 6700 XT aside from in Metro Exodus and Deus Ex: Mankind Divided — two titles we benchmark in configurations that put egregious power on reminiscence bandwidth. There’s no signal of an issue in any name at settings that yield playable body charges. AMD is also advertising and marketing this GPU as a 1440p answer, however it’s completely able to using 4K body charges.

For those who learn different opinions across the web, you’ll to find that the relative hole between the 6700 XT and RTX 3070 levels from 0 – 10 p.c relying on which titles reviewers’ examined. In our take a look at suite, the 6700 XT by no means rather suits the efficiency of the RTX 3070, even at its goal 1440p answer. The RTX 3070 theoretically prices simply 4 p.c greater than the 6700 XT and it’s greater than 4 p.c sooner, in each answer.

Usually, this might be an open-and-shut case, however the high-end ray tracing hit we noticed from each the RTX 2080 and RTX 3070 provides us pause. AMD recommends the 6700 XT be used for 1080p ray tracing, so it’s no longer transparent how a lot ray tracing enthusiasts can be doing in 4K anyway. However in some instances, the 8GB buffers at the RTX 3070 and RTX 2080 aren’t big enough for extremely element settings with RT ladled on best.

The most powerful argument in want of the 6700 XT is the GPU’s 12GB VRAM buffer. The extra VRAM capability obviously buffers the 6700 XT in Godfall at 4K in some way that isn’t defined via it being an AMD-friendly name, and it lets in the 6700 XT to eke out a slim win in Watch Canines Legion after shedding the primary two resolutions. It’s conceivable that the 6700 XT is an extraordinary instance of a GPU whose bigger VRAM capability will ship meaningfully higher cutting down the road when playing cards with much less VRAM are pressured to disable options like ray tracing at decrease resolutions.

I’m in point of fact hoping that the following Giant Navi GPUs AMD declares have the ability to make the most of the cardboard’s chronic potency slightly than depending so closely on clock. If the Radeon 6700 follows the 5700’s lead, it’ll function 36 CUs as an alternative of 40 and a discounted clock. It will be great to peer AMD stay extra CUs at decrease clocks to play up the ability intake perspective; wider, slower GPUs have a tendency to be extra power-efficient than narrower, higher-clocked GPUs.

If the marketplace had been lately standard, I’d argue that the RTX 3070 is the simpler price should you substitute your GPU relatively ceaselessly or sport at 1440p and under, whilst the 6700 XT may well be a more sensible choice should you’re involved concerning the VRAM factor longer-term. I all the time have a tendency to weight the here-and-now extra closely than the long-term long run of any function, and the RTX 3070 provides in most cases sooner efficiency for lower than the extra value of the cardboard in each ray tracing and rasterization.

A $30-$50 worth minimize would do the 6700 XT an international of fine. That is nearer to the place the cardboard should be priced, given its total aggressive efficiency in opposition to the RTX 3070. At $429, the 6700 XT could be a very simple advice for any individual short of to avoid wasting a little of money over the RTX 3070 or to step up from an older AMD or Nvidia GPU.

However marketplace costs aren’t standard and so they aren’t anticipated to be standard till 2022, making this communicate of hypothetical worth comparisons a little foolish. The exact absolute best GPU you’ll be able to purchase at this time is the GPU you’ll be able to get for one thing coming near MSRP, the Radeon 6700 XT very a lot incorporated. With six-year-old playing cards just like the R9 390X going for over $400 on eBay, a $479 price ticket in this newest GPU, will have to you ever see one, is an absolute scouse borrow.
