ASUS launched its Radeon HD 7700 series with two cards, both non-reference design, which take advantage of proven cooler designs ASUS used in previously-launched models. The Radeon HD 7770 card is based on its DirectCU cooler that has been used on a number of upper-mid range graphics cards. Its cooler consists of a heat-pipe fed aluminum fin array, in which the heat-pipes make direct contact with the GPU die. This card bears slightly overclocked speeds, with the core clocked at 1020 MHz (vs. 1000 MHz reference), and 1150 MHz / 4.60 GHz memory (vs. 1125 / 4.50 GHz reference) memory.

The Radeon HD 7750 card from ASUS uses a non-reference PCB and a cooler design which has been implemented on several mid-range graphics cards by the company in the past it is a fan-heatsink with spirally-projecting aluminum fins, with a copper core at the center. The heatsink is ventilated by a large fan, which is known to be very quiet. Like its bigger brother, this card too features slightly overclocked speeds, with the core clocked at 820 MHz (vs. 800 MHz reference), and 1150 MHz / 4.60 GHz memory (vs. 1125 / 4.50 GHz reference) memory. Expect these cards to stick to common prices of US $159 for the HD 7770 and $109 for the HD 7750.

These are essentially based on two designs by the company, a single-fan Ghost Thermal Technology board, and a dual-fan Double Dissipation board, spread across both the HD 7770 and HD 7750 SKUs, and in a variety of factory-overclock bins such as Core Edition (AMD reference speeds), Black Edition (1095 MHz core for the HD 7770, TBD for HD 7750), and SuperOverclock Edition (1120 MHz core for the HD 7770, TBD for the HD 7750).Other specifications and a video presentation by XFX follow.

Sapphire kicked off its Radeon HD 7700 series lineup with a trio of graphics cards, the HD 7700 OC, the Radeon HD 7700 (stock frequencies), and a Radeon HD 7750. All three are based on Sapphire's custom designs. The Radeon HD 7770 cards use a custom-design fan-heatsink with an AMD reference-design PCB that's colored Sapphire's signature shade of blue; while the HD 7750 card uses a fan-heatsink originally designed by Arctic Cooling, which Sapphire used on several mid-range cards in the past. The HD 7770 OC features clock speeds of 1150 MHz core, and 1250 MHz (5.00 GHz effective) memory. The stock-frequency HD 7770 sticks to AMD reference speeds of 1000 MHz core, and 1125 MHz (4.50 GHz effective) memory. The HD 7750 sticks to AMD reference clock speeds of 800 MHz core and 1125 MHz (4.50 GHz effective) memory. Expect most common prices of $159 for the HD 7770 with a small premium for the OC model, and $109 for the HD 7750.

AMD has just launched the new Radeon HD 7700 series, in a bid to cement its competitiveness in the sub-$200 market-segment. The Radeon HD 7700 series, according to AMD, is designed to offer "the world's most advanced graphics for everyone." The series is based around a new ASIC built on the 28 nm fab process, codenamed "Cape Verde". The new chip takes advantage of the Graphics CoreNext architecture, and features 10 GCN compute units, amounting to 640 stream processors; 40 TMUs, and 16 ROPs; and a 128-bit wide GDDR5 memory interface.

The Radeon HD 7770 has all components on the chip enabled, and features clock speeds of 1000 MHz core, and 1125 MHz (4.50 GHz GDDR5 effective) memory, yielding 72 GB/s memory bandwidth. This card draws power from a 6-pin PCIe power connecor. The Radeon HD 7750, on the other hand, features 512 stream processors, and 32 TMUs. The rest of the specifications are identical to the HD 7770, except core clock speed: 800 MHz. The Radeon HD 7770 is priced at US $159, while the HD 7750 is available as low as $109.

In the coming week, AMD will release its Radeon HD 7700 series, which aims to increase its competitiveness in the sub-$200 market. The latest specifications exposé reveals AMD's new design strategy: Instead of increasing components such as stream processors and ROPs, which would increase transistor counts, and unnecessarily increase power draw, AMD is counting on a lesser number of better-configured Graphics CoreNext stream processors. While the previous-generation HD 5770/6770 "Juniper" GPU featured VLIW5 stream processors, the new "Cape Verde" GPU, which will go into making up Radeon HD 7770 and 7750, will feature GCN stream processors. Apart from architectural performance improvements, AMD is counting on increased clock speeds to do the trick. The specifications are listed below.

Cape Verde Physical

• Built on TSMC 28 nm process, ~1.5 billion transistors
• 10 Graphics CoreNext Compute Units (CUs)
• 640 stream processors
• 40 TMUs, 16 ROPs
• 128-bit wide GDDR5 memory interface

First pictures of AMD's mainstream card, HD 7770, have now been leaked online. This card is the first major upgrade to the HD 5770 in two years, since the HD 6770 was just a rebrand. It features the Cape Verde GPU, which replaces the Juniper GPU used in the HD 5770/HD 6770. The card looks somewhat different, with a large fan sitting on top of the GPU, blowing directly onto it and the card's length is the same as the HD 5770, at around 8.25 inches.
