AMD Radeon HD 7700 Series: We know the different models available.
As expected, the AMD Radeon HD 7770 and HD 7750 have already been launched, two graphics cards based on the Graphic Core Next architecture and manufactured in 28nm that AMD puts on the market. We already discussed it yesterday in SamaGame, now we are going to see the different models that manufacturers have prepared.
The reference model that AMD puts on the market is now joined by the models that the main manufacturers prepare with various improvements and customizations such as in the aspect of cooling or design of the graphics card. Let’s see what they offer us.
AMD reference design.
Let’s start with Asus for example.
Well, the manufacturer Asus has launched its particular versions of the HD 7770 and HD 7750, both come with improvements in the cooling system and with a bit of overclocking.
Asus Radeon HD 7770 DirectCU.
For this occasion, Asus has chosen to use the DirectCU heatsink for its HD 7770, thus improving cooling and achieving less noise compared to the reference model. Their frequencies are located at 1,020Mhz for the core and at 1,150Mhz for the memory. It is a slight overclock since the serial frequencies are located at 1,000Mhz for the core and 1,125Mhz for the memory.

With the HD 7750 the reference design has not been used either, the heatsink has been replaced by a larger one and made of aluminum with a copper base. It also comes to us with a slight overclock and its frequencies are set at 820Mhz for the core and 1,150Mhz for its memory. But it is an overclock similar to that of its older sister, slight, the reference values are located at 800Mhz for the core and 1,125Mhz for its memory.
We turn to the manufacturer HIS that also presents us with two models.
HIS Radeon HD 7770 Ghz Edition.
The HD 7770 Ghz Edition arrives with the frequencies of the AMD reference model, in this case HIS has only slightly modified the cooling system and the color of the graphics in general.
HIS Radeon HD 7750 iCooler.
As with the previous graph, their operating frequencies have not been modified with respect to the reference model, only the heatsink has been changed for a more efficient one.
We are going to stop at XFX because this manufacturer has released nine HD 7700 Series graphics cards. In all the cooling has been improved, making use of the cooling that they call Ghost Thermal Technology and Double Dissipation for both graphics. In the Core Edition versions the reference frequencies are used, while in the Black Edition and SuperOverclock Edition versions they add overclock for the HD 7770, with 1,095Mhz and 1,120Mhz for the cores respectively. For the HD 7750, the overclock they carry has yet to be determined.

Time for PowerColor, here they have not been much complicated and they are basically the same models that AMD offers but with the sticker changed. Although in the case of the PowerColor HD 7750 the heatsink has been changed a bit. The operating frequencies are those of AMD series.

Club3D has not modified the design of its Radeon HD 7770 and Radeon HD 7750 either, both also come with the reference frequencies.

Closing the group of manufacturers that have hardly changed the design of the HD 7700 Series graphics, we have VTX3D, which also maintains the serial frequencies.

Sapphire in this case has released three different graphics cards, the HD 7770, the HD 7770 OC and the HD 7750. The HD 7770 and HD 7750 make use of AMD’s stock clocks, while the HD 7770 OC is offered with a single core. that works at 1,150Mhz and a memory that works at 5,000Mhz effective. All three models use a custom Sapphire heatsink.

MSI could not be less and has launched its fully customized HD 7770 and HD 7750 graphics. The MSI HD 7770 presents a small overclock in the GPU that places its frequency at 1,020Mhz and maintains the memory frequency. For the HD 7750 the GPU has also been slightly overclocked to 830Mhz. The heatsink has also been considerably improved and includes two 80-millimeter fans to improve its cooling capacity.

We finish this review of the graphics cards launched by manufacturers with Gigabyte, which presents three models. The HD 7770 GV-R777D5-1GD that comes with the standard frequencies, the Radeon HD 7770 GV-R777OC-1GD that is overclocked to 1,100Mhz on the core and the Radeon HD 7750 GV-R775OC-1GI that is overclocked to 880Mhz on the nucleus. The heatsink has been improved and now includes a 100-millimeter fan with which better temperatures and less noise are achieved.
