the first test shameless card ati radeon hd 4770   Go to a more delicate manufacturing process gives the developer a chance to break forward. He may have received in their own hands an advantage in many ways. As for the graphics adapters, the chips manufactured in compliance with 40-nm technology standards, reduce energy consumption, increase the working frequency and reduce the noise from the refrigeration system. In addition, there still remains the possibility of manipulating the price, suggesting a more efficient solution than that of a competitor even for less money. Today we see of what the latest graphics adapter ATI Radeon HD 4770. And why we called it unconscionable, will become clear when the issue touches comparing it with other solutions.
The reader will certainly have time to get acquainted with the presentation slides ATI Radeon HD 4770, if not, recall the address. The main characteristics are displayed in the screenshot utility GPU-Z and in the comparative table.
Graphic Adapter ATI Radeon HD 4770 has 640 stream processors, 32 texture units and 16 modules rasterizatsii (ROP). The utility GPU-Z is wrong for the determination of the number of blocks rasterizatsii. Novelty has on board 512 MB high-speed GDDR5 memory with a bandwidth 51, 2 Gb/s and 128-bit interface that operates at a frequency of 800 MHz, while the operating frequency of graphic core is 750 MHz.
The measurement of energy consumption indicate that in the idle power consumption ATI Radeon HD 4770 still can be equal with other decisions, then everything becomes a burden to their seats. Video cards, memory chips which are made in accordance with rules 55-nm production methods, demonstrate significantly worse outcomes.
A test system that allows our colleagues from the resource Expreview.com conducted a test is presented below.
Radeon HD 4770 to Radeon HD 4830 (640 stream processors).
What`s there to say. Beautiful. Approximately 9% of all maintained the advantage. A higher clock frequency kernel is doing its part. Let`s look at the results of comparison Radeon HD 4770 and Radeon HD 4850.
In this hard to believe, but the Radeon HD 4770 dared to fall behind at 6% of the Radeon HD 4850. Recall that in an asset Radeon HD 4850 has 800 stream processors. More interestingly, Radeon HD 4770 against the GeForce 9800GT. Ready ?
Newbie has allowed me to circumvent the GeForce 9800GT graphics card by about 19%, on average, result in all tests. To consolidate the Radeon HD 4770 against the GeForce GTS 250.
The delay of the Radeon HD 4770 GeForce GTS 250 is only 8%, which is at a different value of these solutions is not so impressive.
overtaking even the central processor in terms of technology, Radeon HD 4770 for its $ 100 shows an impressive performance. A new round of competition began. We are waiting for a response NVIDIA.
