The Clash Of The Middle Class – Part 5 – Sapphire Radeon HD 7770 Vapor-X

Sapphire Radeon HD 7770 Vapor-XAs we said this is the second part of the comparison, where the opposition will be shown. It is firstly represented by the leader in AMD GPU production- the Sapphire 7770 card, which has been equipped in the Vapor-X clotting, even though this was formerly reserved for the high end cards.

Because Cape Verde- the chip that is on the HD 7700 is a low consumer chip, Sapphire has designed a reduced version of their cooler Vapor-X, while keeping the main characteristics the same. For example, the vapor chamber is made out of copper, which is essentially a big heatpipe. Also, it has two really quiet coolers that have a specific curvature at the end. The cooling profile is made out of aluminum, which is pretty big for its class. The cooling system is really good, giving out maximum 60°C, while working on full thrust.

Under the coolant it has a GPU chip manufactured in 28nm process that has 640 stream processors, as well as 16 ROP- or 40 texture units. The processor is based on GCN architecture, so it has everything that the older brothers have. This means it has Eyefinity2.0, AMD HD3D and other tech, which is really good move by AMD.

The memory system is made out of four chips, with a total capacity of 1GB, which communicates with the GPU through a 128-bit interface. The factory overclock is a must here and Sapphire has gone furthest, overclocking it up to 1100MHz per core, which is a really big result and with the combination of implementing the fastest memory that runs effectively on 5200MHz, the Vapor-X brings the best results from all the tested cards.

When it comes to connections except for the PCI-Express 3.0 and a six-pin molex, it has a CrossFireX connector. And considering the video connection types supported, it has a vast choice: two DVI, one HDMI and one DisplayPort.
