Today we look at two new video cards from VTX3D – the HD7790 and HD7850 VChamp Edition. The VChamp cooler is the latest from the company, incorporating a Vapor Chamber for faster heat dissipation.
Are these models worthy of being shortlisted for a new system build?
VTX3D say they are using solid capacitors on both cards with shielded inductors. They have upped the power phase to 5+1+1 on their HD7850 and 4+1+1 on their HD7790 model. Both coolers are a Vapor Chamber design and have dual 80mm fans on board to help improve cooling performance.
The VTX3D VChamp HD7850 receives a core clock boost from 860mhz to 1,000mhz and the memory is also increased from 1,200mhz to 1,225mhz (4.9Gbps effective). The HD7850 is a cost effective graphics card, especially if you want to game at 1080p without spending a fortune.
The VTX3D VChamp HD7790 receives a core clock increase from 1,000mhz to 1,075mhz and the memory speed runs at 1,500mhz (6Gbps effective). This card was welcomed on release as a capable replacement for the rather lackluster HD7770. AMD increased the shader power from 640 to 896 Stream Processors from HD7770 to HD7790.
