GPU Benchmarks

NVIDIA’s RTX 5090 (24 GB GDDR6X, 300 W TDP) and AMD’s Radeon RX 7900 XTX (24 GB GDDR6, 350 W TDP) lead the 2026 GPU benchmark hierarchy. In 3DMark Time Spy, the RTX 5090 records a score of 23,800, outpacing the RX 7900 XTX by 8 %. In Blender GPU rendering, the RTX 5090 completes a 1920×1080 scene in 45 seconds, versus 58 seconds for the RX 7900 XTX.

These results underscore the RTX 5090’s superiority in ray‑tracing and AI‑accelerated workloads, making it the optimal choice for high‑end workstations and enthusiast rigs.

Memory and Storage Benchmarks

DDR5‑6400 kits (e.g., Corsair Vengeance DDR5 6400MHz 128GB) achieve latency timings of CL30‑36 and bandwidth of 51.2 GB/s per channel, delivering up to 20 % higher memory throughput than DDR4‑3600. In PCMark 10 Storage, the Samsung 990 Pro 4TB NVMe SSD reaches 7,200 MB/s sequential read and 6,800 MB/s write, eclipsing the previous generation 970 EVO Plus by 15 %.

4. Mount the CPU Cooler

5. Attach the mounting brackets for the Noctua NH‑D15 to the motherboard’s backplate, following the provided instructions.
6. Secure the cooler’s base onto the CPU, ensuring even pressure across the surface.
7. Connect the fan header to the CPU_FAN header on the motherboard.

5. Install RAM Modules

8. Identify the dual‑channel slots (typically slots A2 and B2) on the motherboard.
9. Release the clips on each DIMM slot, align the notch on the Corsair Vengeance DDR5 6400MHz 128GB module, and press down firmly until the clips snap.
10. Repeat for all four modules to populate the 128 GB capacity.
