Precision at
31.25 Picoseconds
When a single bit lives for 31.25 trillionths of a second, every atom of copper, every micron of gold, every milliohm of impedance determines whether your GPU runs at full bandwidth — or negotiates down.
Speed Is Easy.
Signal Integrity Is Hard.
PCIe 5.0 doubles Gen 4 throughput. Without deliberate engineering at the physical layer, that speed is theoretical — your GPU negotiates down before the OS loads.
Three Physics Problems
Intersymbol Interference. At 31.25 ps per bit, pulses overlap at the receiver. Per-pair aluminum foil shielding isolates every differential lane — no crosstalk, no symbol corruption.
Impedance Mismatch. A 5% deviation from the 85Ω target creates return loss that closes the eye diagram. Our 40-pin connectors are machined to ≤3% across all 164 contact points.
Antenna Effect. At 16 GHz Nyquist, the cable behaves as an antenna. PSU rails, VRM switching noise, and even RGB PWM inject EMI. The overall braided shield absorbs external interference before it reaches the signal path.
Full specifications →Most similar setups are limited by the PCIe bus version due to the challenges of running longer PCIe extensions.
Calculated by Length.
