Key takeaways
- RX 6700 XT: $479 for a performance index of 100 = $4.79 per point
- RX 9070: $549 for a performance index of roughly 190–200 = about $2.75–$2.90 per point
Yes, upgrading from the RX 6700 XT to the RX 9070 is worth it if you game at 1440p or want usable ray tracing and FSR 4, because reviews show the RX 9070 delivering roughly double the frame rate at 1440p for about the same power draw. If you play mostly esports titles at 1080p and your 6700 XT still holds your monitor’s refresh rate, you can comfortably wait another generation.
This is one of the cleanest upgrade paths in AMD’s lineup: same vendor, same driver suite, similar power envelope, and the same 267 mm reference length. What changes is the performance class, the memory configuration and the feature set. Here is what you actually gain.

| VRAM | 12 GB GDDR6 | 16 GB GDDR6 |
| Memory bus | 192-bit | 256-bit |
| Memory bandwidth | 384.0 GB/s | 644.6 GB/s |
| L2 / Infinity Cache | 3 MB / 96 MB | 8 MB / 64 MB |

On paper the shader count rises by 40% and bandwidth by about 68%, while the rated TDP actually falls by 10 W. RDNA 4 also reworks the compute units, ray tracing hardware and adds dedicated AI acceleration, so the real-world gains are larger than the raw numbers suggest.
How Big Is the Jump in Games?
1440p: the sweet spot for this upgrade
Hardware Unboxed’s long-term look at six years of mid-range Radeon cards (published on TechSpot) is the most direct comparison available. At 1440p the RX 9070 was roughly 80% to over 100% faster than the RX 6700 XT depending on the game: around 87% in Call of Duty: Black Ops 6, about 97% in Cyberpunk 2077: Phantom Liberty, roughly 103% in Horizon Zero Dawn Remastered and close to 130% in Rainbow Six Siege X. A rough overall summary: expect about twice the frame rate at 1440p.
In approximate terms, a game that runs at 45–55 FPS on high settings on the 6700 XT at 1440p will often land in the 90–110 FPS area on the RX 9070. These figures vary with settings, CPU and game patches, but the scale of the jump is consistent across reviews.
1080p
The gap shrinks at 1080p, mostly because the CPU becomes the limit sooner. Hardware Unboxed’s data still shows gains of roughly 60–90% in demanding titles, but if you pair the RX 9070 with an older CPU such as a Ryzen 5 3600, expect a meaningful part of that uplift to disappear in CPU-heavy games.
4K
At 4K the RX 9070 pulls even further ahead, with some games more than doubling the 6700 XT’s result. The 6700 XT was never a 4K card; the RX 9070 can handle 4K at medium-high settings with FSR 4 upscaling in many titles.
Ray tracing
This is where RDNA 2 shows its age. The 6700 XT’s first-generation ray accelerators struggle with anything beyond light RT effects. RDNA 4’s redesigned RT units narrow the gap with NVIDIA considerably, and published reviews show RT gains over RDNA 2 that are larger than the raster gains, often well over double. Heavy path tracing is still NVIDIA’s territory, but RT reflections and global illumination at 1440p become genuinely playable on the RX 9070.
FSR 4 Is a Bigger Deal Than It Looks
The RX 6700 XT supports FSR 3.1 upscaling and frame generation, plus AMD Fluid Motion Frames at driver level. Those work, but FSR 3’s upscaler shows shimmering and fizzle on fine detail, especially at 1080p and in Performance mode.
FSR 4 is a machine-learning upscaler that runs on RDNA 4’s AI hardware, and officially it is exclusive to RX 9000 cards. Reviewers broadly agree it is a large image-quality step over FSR 3 and competitive with NVIDIA’s DLSS 3-era upscaling. Game support is smaller than DLSS, but many FSR 3.1 titles can be upgraded to FSR 4 through the AMD driver. In practice this means you can run FSR 4 “Quality” or even “Balanced” at 1440p without the visible artifacts that pushed many 6700 XT owners to native resolution.
Worked Example: Cost per Unit of Performance
Using launch MSRPs and Hardware Unboxed’s roughly 2x figure at 1440p:
- RX 6700 XT: $479 for a performance index of 100 = $4.79 per point
- RX 9070: $549 for a performance index of roughly 190–200 = about $2.75–$2.90 per point
At launch prices, the RX 9070 delivers around 40% better value per frame than the 6700 XT did, while adding 4 GB of VRAM and a newer feature set. If you sell your 6700 XT, the effective upgrade cost falls further. A used 6700 XT usually sells for roughly $180–$230, which cuts the net cost of a $549 RX 9070 to somewhere around $320–$370 for double the 1440p performance.
VRAM: 12 GB to 16 GB
The 6700 XT’s 12 GB has aged well compared with 8 GB cards, and most current games at 1440p fit inside it. Where 12 GB starts to pinch is 1440p with high-resolution textures plus ray tracing, or 4K. The RX 9070’s 16 GB on a 256-bit bus adds headroom for those cases and for frame generation, which needs extra memory. As a rough guide:
- 1080p high: 8–10 GB comfortable
- 1440p high with RT: 12 GB workable, 16 GB comfortable
- 4K high: 16 GB is the realistic floor for newer releases
Power Supply and Case Check
The power side of this upgrade is unusually easy. Using the rule of thumb of GPU TDP + CPU power + about 150 W headroom:
- RX 6700 XT build with a 105 W-class CPU: 230 + 105 + 150 = about 485 W
- RX 9070 build with the same CPU: 220 + 105 + 150 = about 475 W
If your current 6700 XT system runs on a quality 650 W unit, the RX 9070 will run on it too. The one change is connectors: the reference 6700 XT uses a 6-pin plus an 8-pin, while the RX 9070 uses two 8-pin connectors. Most 550–650 W power supplies have two PCIe 8-pin (6+2) leads, but confirm before ordering. Factory-overclocked partner RX 9070 models can ship with higher power limits than the reference figure, so check the board you buy.
The reference length is the same 267 mm and both are dual-slot designs, but many partner RX 9070 cards are triple-fan and longer than 300 mm. Measure your case’s GPU clearance before choosing a specific model.
Does PCIe 5.0 Matter?
The RX 9070 uses a PCIe 5.0 x16 interface, but it runs fine in PCIe 4.0 and even PCIe 3.0 slots. With 16 GB of VRAM and a full x16 link, the bandwidth difference in games is small. You do not need a new motherboard for this upgrade, though enabling Smart Access Memory (Resizable BAR) in the BIOS is recommended.
When the Upgrade Pays Off and When It Doesn’t
| Your setup | Upgrade verdict |
|---|---|
| 1440p 144–165 Hz monitor, modern AAA games | Strong yes: roughly 2x frame rates |
| Want ray tracing or better upscaling | Yes: RDNA 4 RT and FSR 4 are big steps |
| Moving to 4K or ultrawide 1440p | Yes, with FSR 4 in demanding games |
| 1080p esports, CPU older than Ryzen 5000 / Intel 12th gen | Upgrade the CPU first |
| 1080p 60 Hz, happy with current performance | Not needed yet |
| Tight budget, 6700 XT still fine | Wait; consider used prices later |
Driver and Software Notes
Both cards use AMD’s Adrenalin software, so there is no driver learning curve. RDNA 4 owners get the newest features first, including FSR 4 overrides and the newer AI-based features AMD is rolling out for RX 9000. Hardware Unboxed also noted in later testing that the RX 9070 gained performance over time through driver and game updates, which is a good sign for its longevity. RDNA 2 still receives game-ready drivers, but new features increasingly target newer architectures.
Frequently Asked Questions
How much faster is the RX 9070 than the RX 6700 XT?
Hardware Unboxed’s comparison shows the RX 9070 roughly 80% to over 100% faster at 1440p, depending on the game. At 1080p the gain is somewhat smaller because the CPU limits frame rates sooner. At 4K the gap is larger still.
Can I use FSR 4 on the RX 6700 XT?
Officially, no. FSR 4 relies on the AI hardware in RDNA 4 and is supported on RX 9000 series cards. The 6700 XT is limited to FSR 3.1 upscaling and frame generation, plus driver-level Fluid Motion Frames.
Do I need a new power supply to upgrade to the RX 9070?
Usually not. The RX 9070 is rated at 220 W, slightly below the 6700 XT’s 230 W. A quality 650 W unit with two PCIe 8-pin leads is enough for most builds. Check connector count and the specific partner card’s power requirements.
Will the RX 9070 be bottlenecked by my CPU?
At 1440p and 4K, a Ryzen 5 5600 or Intel 12th-gen Core i5 or newer will let the RX 9070 stretch its legs in most games. At 1080p, older CPUs such as Ryzen 3000 series can hold the card back noticeably. If you game at 1080p high refresh, budget for a CPU upgrade too.
Should I buy an RX 9070 XT instead?
The RX 9070 XT is faster but draws noticeably more power and launched at $599. The non-XT RX 9070 is the more efficient option and a better fit for systems that previously ran a 6700 XT. If the price gap between them is small where you shop, the XT offers more performance for 4K.
