Alternate.de has it for €66 Sapphire's HD 4670 is the first HD4600 series card to be available in E.U., at least according to the European price search engine Geizhals.at. Bear in mind that this is still launch day, and we're expecting the HD4670 to be widely available within hours. The HD4650 comes a couple of weeks later. The card is packed in a light retail pack and sells for €66, including 19 percent of tax in Germany. It works at 750MHz for the core and comes with 512MB of GDDR3 memory clocked at 1,000MHz (2,000MHz). It is cooled by a small fan combined by a single slot heatsink and has a blue PCB, something that is traditional to Sapphire. You can find the card listed here, and you can buy it from Alternate.de here. The price will eventually drop a bit more but if you need to have it now and you are living in Germany, Alternate is the first retailer to have it.

Donanimhaber released pictures of the upcoming ASUS Radeon HD 4670 graphics card (model EAH4670). The card is based on the newer graphics processor from ATI, the RV730. There are two models by ASUS lined up for release. The first one being a standard 512 MB GDDR3 model, and another 1 GB model. The card provides HDMI port onboard, neighboured by D-Sub and DVI connectors. The card supports ATI Crossfire X. The card features a custom design by ASUS. A rather large GPU cooler that spans across two slots is featured. It is advertised to keep the GPU 15 °C cooler than the reference cooler. Specifications wise, the card features GDDR3 memory clocked at 2008 MHz, with the core at 750 MHz. It is HDCP compliant.

Palit Microsystems, leading graphics card manufacturer, follows up the release of HD 4850 Sonic by introducing the astonishing HD 4850 1GB Sonic equipped with 1024MB king size memory along with pre-overclocked 2000MHz memory speed and 685MHz core speed combining Palit’s own design innovative cooling system and power management technology offering another amazing choice to performance hunters. Palit HD 4850 1GB Sonic edition, as the 1GB Sonic naming implies, has 1024MB king size memory along with pre-overclocked 2000MHz memory speed and 685MHz core speed. This card is able to provide stunning graphics performance while offering extra memory buffer, allowing users to enjoy extreme performance improvements while playing the latest DX10 PC games under HD large screen and high quality image (such as 8xAA.).

تصویر بزرگتر و واضحتر is known that one of the three bloomfield models will get the unlocked multiplier and relate to the core i7 extreme edition series, and the two others will form the series core i7. Associate published another screen shot Of bloomfield model, obtained with the aid of same CPU- Z version. According to this utility, bloomfield processor with 2.93 GHz frequency will get the name core i7 940. The 940 index was used by the 65 nm dual core processor Pentium D with 3.2 GHz frequency . Here is also the motherboard gigabyte X58-DS4 on base of Intel x58 chipset with LGA 1366 socket and six DIMM slots.

already reported at the end of past month that during the first days of September AMD will lower the prices of its desktop processors. Let us note that the prices reductions of elder models phenom X4 proved to be even more generous, which as it was expected is up to 26%. Furthermore, other processors models fell in price to the value from 9% to 24%. The dual core processors athlon X2 5800+ was removed just like processors with rating lower than 5000+.

Holland-based Nexus unveiled today what's I believe the first cooling reported on our site to support Intel Socket LGA 1366. That's the same socket that will be used with Intel's next-gen Core i7 processors, scheduled to be released later this year (Q4 2008). Made out of pure copper, the Nexus FLC-3000 houses a rather unusual design, measuring 128 (L) x 105 (W) x 119 (H) mm. It weights in 450 grams, has an aluminum heatsink and four 6mm copper heatpipes angled at 30 degrees. The cooling surface is chilled by a 90mm RPM-controlled fan that works between 900 and 2500 RPM and has a sound output between 15 dB(A) and 24 dB(A) depending on the rotation speed. The fan is also equipped with two orange LEDs. In addition, the Nexus FLC-3000 is also Intel LGA 775 and AMD AM2/AM2+ socket compatible. The cooler is yet to be priced.

Pre-release 3DMark tests show that two Radeon HD 4670 graphics cards in Crossfire multi-GPU mode outperforms a single Radeon HD 4850 card. The HD 4670 cards score just a little above the HD 4850 in three tests that include 3DMark06 in Shader Model 2.0 mode, the same benchmark in SM 3.0 mode and 3DMark Vantage. The cards scored 54xx 3DMarks in SM2.0 and 65xx 3DMarks in SM3.0 tests, a 4850 on the same test-bed produced 49xx and 57xx respectively. With 3DMark Vantage, the Crossfire setup churned out 7300, with the single HD 4850 just 100 points behind at 7200. These scores can be attributed to the raw texturing power the HD 4670 cards have despite memory bandwidth advantage staying with the single HD 4850. Indications are that the HD 4650 won't scale as well since (at least reference models) lack hardware Crossfire.

درود واقعا تست های خوبی بود و در نوع خودش در ایران کمتر کسی با قطعات های اند اینچنین تست هایی رو انجام میدهد.

After NVIDIA canned the Hybrid Power on MCP7A and pushed back the release date to August, we did not heard about any updates of the chipset from motherboard vendors for a long time. But today we received new date change from our sources. One of our sources mentions that MCP7A will hit the market in the late September. But it seems MSI and ECS want to announce the board earlier than others. MSI has already sent out a press release of their nForce 730i/GeForce 9300 mobo P7NGM. Also ECS have updated their website for the newly released mobo GF9300T-A. If NVIDIA still keeps the date than we can get MCP7A in the end of this month.

درود دوست عزیز خواهشا عنوان تاپیک را مختصر و مفید انتخاب کنید که نظم صفحه اول را به هم نزنه. این بار پست های شما رو ویرایش کردم اما در صورت تکرار در دفعات آینده پست های با عنوان طولانی که نظم صفحه اول را بهم بزنه پاک خواهد شد.

درود رضا جان ظاهرا GF9800 GT تفاوت چندانی در کارایی با GF8800 GT ندارد و در اکثر تستها نتایج برابری رو داشتند و در تعداد کمی از بنچمارکها 9800 جی تی برتری ناچیزی رو داشته.

Gigabyte might well be the first AIB partner for ATI to release the first passively cooled Radeon HD 4850 accelerator, and a 1 GB one at that. The Gigabyte GV-R485MC-1GH sports the RV770 graphics processor clocked at 625 MHz and 1 GB of GDDR3 memory clocked at 1.00 GHz. Gigabyte is to use its "Multi-Core" passive cooler that consists of two arrays of aluminum fins, with two copper heatpipes each conveying heat from the core to the fin arrays. The card will feature Ultra Durable 2 high-grade electrical circuitry with what vaguely looks like a 4 + 2 phase power design. The GV-R485MC-1GH will be available soon. Word is that PowerColor would follow Gigabyte with their passively cooled Radeon HD 4850 model.
