Notes on 7 values — test conditions and caveats
  1. 1AMD Radeon RX 9070 XT, Launch price: TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.
  2. 2AMD Radeon RX 9070 XT, Boost clock: TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.
  3. 3NVIDIA GeForce RTX 5090, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  4. 4AMD Radeon RX 9070 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
  5. 5AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
  6. 6NVIDIA GeForce RTX 5090, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  7. 7NVIDIA GeForce RTX 5090, Slot width: The card is 2-slot, but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.

Performance and Compute

The NVIDIA GeForce RTX 5090 dominates in raw processing power with 21,760 shader cores and 104.8 TFLOPS of FP32 compute. This massive architecture handles heavy workloads far faster than the competition.

The AMD Radeon RX 9070 XT relies on 4,096 cores and 48.7 TFLOPS. While it delivers a higher boost clock of 2,970 MHz, it targets a completely different tier of computing capability.

Memory and Bandwidth

NVIDIA equips its flagship with 32 GB of GDDR7 memory across a 512-bit bus, driving a massive 1,792 GB/s bandwidth and 28 Gbps speed. A larger 96 MB last-level cache supports these specs for extreme multitasking.

The AMD card features 16 GB of GDDR6 memory on a 256-bit bus, delivering 640 GB/s bandwidth at 20 Gbps alongside a 64 MB cache. This setup handles standard high-resolution tasks without requiring top-tier server-grade memory.

Power and System Demands

Running the RTX 5090 requires a robust power supply, demanding a 1,000 W PSU minimum alongside a 575 W board power and a 12V-2x6 connector. It also requires a 2-slot card that needs 3-slot clearance in your case.

The Radeon RX 9070 XT sips significantly less energy with a 304 W board power and a modest 750 W recommended PSU. It uses standard 8-pin connectors for easier integration into existing builds.
