AMD is making a new addition to its midrange graphics card lineup today with the introduction of the Radeon HD 4770 videocard, based on the companies first 40nm GPU, the RV740. The Radeon HD 4770 strikes a balance between performance and price, coming just under the lucrative $100 mark and slotting in nicely in terms of performance between existing Radeon 4670 and 4850 videocards.
ASUS introduced the new ASUS EAH4770 Series that utilizes the Voltage Tweak technology. With this cutting-edge innovation, users will be able to boost GPU voltages via the SmartDoctor application and enjoy up to an 35% performance improvement with the EAH4770 TOP.
Along with the latest GPU technologies that include a 40nm manufacturing process, DirectX 10.1 graphics capabilities, support for HDMI 1.3, CrossFireX, and Stream technology, the ASUS EAH4770 Series is evidence that high performance gaming and affordability can co-exist without compromise.
Equipped with Voltage Tweak technology and the SmartDoctor application, the ASUS EAH4770 TOP/HTDI/512MD5 raises GPU voltages from 0.95V to 1.2V, boosting GPU and memory clock frequencies from 800MHz to 971MHz and 3400MHz to 4600MHz respectively.
The ASUS SmartDoctor is an industry-leading overclocking utility that works in tandem with Voltage Tweak technology to enable users to manually adjust the GPU voltage on the EAH4770 Series. With just a few simple clicks, users will be able to enjoy astounding voltage boosts and performance upgrades - all without the hassle of re-flashing the BIOS at the risk of damaging the cards, or groping blindly for a overclocking button at the back of the chassis.
ATI's new RV740 GPU is derived from the venerable RV770 core, but clocked at 750MHz and equipped GDDR5 memory that runs at an even 800MHz, giving it a memory bandwidth of 51.2 GB/s. The memory bus on the Radeon HD 4770 is 128-bit wide, which should make for an interesting comparison between it and the popular Radeon HD 4850. PCSTATS will break down all the numbers in a moment, but first let's introduce the videocard sitting on the PCSTATS' test bench today, the ASUS EAH4770 HTDI/512MD5/A.
ASUS' EAH4770 videocard is largely based off AMD's reference design, although it does use a simpler two-slot wide aluminum heatsink in place of the standard ATI thermal solution. It's not pretty but it is quiet, that's what matters most. The EAH4770 is PCI Express 2.0 x16 compliant, comes with 512MB of GDDR5 memory and the usual list of supported features; ATI CrossfireX, HDCP, DX10.1, SM4.1, and Unified Video Decoder 2 for HD content decoding.
The EAH4770 Series also incorporates ATI Stream technology, which utilizes the massive parallel processing power of AMD graphics processors to deliver new capabilities that go beyond the traditional usage scenarios of graphics rendering and video processing.
