Verdict
At $799.00, the RX 6700 XT costs about 19% less than the $989.87 Radeon RX 7800 XT. That $190.87 saving is real money, but not so wide that the pricier card is out of reach.
The Radeon RX 7800 XT's 16 GB of VRAM is a 4 GB advantage over the RX 6700 XT. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
