Pros & Cons
Pros
- ✓ 16GB GDDR6X at 23 Gbps feeds 4K texture loads without VRAM swapping
- ✓ 2595 MHz extreme boost clock, factory OC above reference RTX 4080 Super spec
- ✓ Ada Lovelace cores handle ray tracing and DLSS frame generation natively
- ✓ Tri-frozr 3X cooler spreads heat across three fans for lower sustained temps
- ✓ Four displays at once: 2x DisplayPort 1.4a plus 2x HDMI 2.1a
Cons
- ✗ 256-bit memory bus is narrower than the 384-bit RTX 4090 above it
- ✗ 3-fan Ventus shroud is a 3-slot class card, tight in compact ATX cases
- ✗ No DisplayPort 2.1, so 4K 240Hz monitors lean on DSC over DP 1.4a
- ✗ Priced well above MSRP-class 4080 Super listings at current street pricing
