HD4770 power consumption is only 80W
RV790 HD4890 has basically been settled, then the next people will naturally look to the 40nm RV740 body. Recently, Fudzilla has finally been on the ATI HD4770 more detailed information.
HD4770 core RV740, it will be listed on the first use of 40nm process GPU desktop graphics card. Its GPU core frequency will be 750MHz, the use of 512MB GDDR5 memory, memory frequency 800x4MHz, memory interface 128bit. Power consumption, this card will reach 80W, this value than the PCI-E slot can provide maximum power greater 5W, and therefore may require an external power cord. Necessary to remind everyone here, this is not finally determined by the frequency / power consumption value, in the numerical happened up there is probably some minor changes. HD4770 listing date has been scheduled for May 4 at which the week. Price based on a previous message is about 119 U.S. dollars (about 820 yuan)
As for HD4750, AMD did not reveal the slightest tone. However, this should be the same based on a 40nm RV740 GPU products, but the allocation of memory are used GDDR3, memory bit will remain for the 128bit. We believe that this card should be Do not need an external power supply. Price about 99 U.S. dollars (about 670 yuan)
Both graphics cards have the 640 stream processor units and 32 texture units.
AMD hopes to HD4770 graphics cards to replace the existing HD4830 against Nvidia’s 9800GT, and HD4750 use HD4650 to replace the existing confrontation 9600GT.
AMD has just released this month, the catalyst 9.3 display driver package, not only has the formal support of Windows 7 operating system, such as the four major new features, but also to enhance the performance of some of the game and solve various systems of a number of bug, really can be called heavyweight Published. Starting today, AMD and begin to provide the official version of Mobility Radeon HD series graphics card driver has.
AMD has already begun to distributors / retailers bulk supply HD4890 graphics cards. However, they apparently did not comply with AMD’s release date limit, one after another to arrive into the market ahead of the HD4890. HD4890 can support the catalyst 9.4 driver has not yet formally released, more than the HD4890 graphics card vendors products have been emerging in the market, go home and buy a test user. Which I do not know the use of the existing version of Catalyst 9.3 and HD4890 test should not really show its strength.
Better to manage large-scale listing of a product is an arduous task, the first batch of HD4890 listed in excess of 40,000, and to the end of the second quarter sales target is 10,000 25-30. Such sales are considerable, but also prove that there is virtual HD4890 is not a map table.
Now everything is money, a catalyst for the team can release a few days ago it announced a new version of drivers? Of course, AMD may also be taken when the HD4850 was introduced as a strategy, that is, first launched beta version of Catalyst drivers, and then launched an official version of driver.
