Triplex Designs Radeon HD 4830 Without Auxiliary Power Connector
A relatively unknown company, Triplex, has designed a Radeon HD 4830 graphics accelerator that does not require the 6-pin PCI-Express power connector. This is especially interesting for two reasons: that it is RV770, and that it runs at reference clock speeds despite shedding its traditional power design. Spotted on XtremeSystems, this engineering sample PCB features a 2+1 phase power design, that draws all its power from the PCI-Express slot.
Also featured are 512 MB of 256-bit GDDR3 memory, DVI-D, HDMI and D-Sub outputs, and a seemingly two-slot cooler design that is yet to be pictured. The card lacks CrossFireX fingers. The GPU has 640 stream processors, DirectX 10.1 compliance, and a 256-bit memory interface. It has AMD reference clock speeds of 575/900 MHz (core/memory). For reference the third picture shows a Radeon HD 4670 accelerator of the same make, and PCB length.
