با سلام.

دوستان 260 gtx قويتره يا 4870 ? طبق مقايسه بالا 260 gtx. ولي تو خيلي سايتها نتايج به نفع 4870 است.البته همونطور كه ميدونيد منبع تست بالا سايت بسيار معتبريه.نظر دوستان چيه؟

دوست عزیز به طور کلی GTX 260 فاصله کمی رو با 4870 داره.به این صورت که در بعضی موارد 4870 جلوتر هست و در بعضی موارد GTX 260 و البته باز این اختلاف نتایج در نرم افزار ها و بازیهای مختلف سایتهای مختلف و در روزلیشن های متفاوت بیشتر متغیر هست ولی به طور کلی 4870 به دیلیل بهر مندی از حافظه گرافیکی GDDR5 از برتری بیشتری برخوردار هست.

سلام.

از لحاظ مصرف چطورند؟منظورم 260 gtx در مقابل 4870؟

نتيجه اي كه ميشه گرفت اينه كه اول ما بايد مشخص كنيم تو چه رزولوشني ميخوايم بازي كنيم.اين خيلي مهمه.مثلا در crysis در رزولوشن 1280*1024 حتي در hight detail يك كارت 8800 gtx هم كفايت ميكنه.كه اونم با اين قيمتي كه تو ايران داره خوب ادم با خودش ميگه يا همون 4870 رو ميگيرم يا 260 gtx.

Since the geForce 9800 GT is the successors Of geForce 8800 GT, the majority of NVIDIA partners released many alternative versions. Gigabyte company , for example, presented the video card GV-N98TZL-512H with 512 MB memory and Zalman cooler .

In the near future gigabyte will release the version GV-N98TZL-1GH with 1Gb GDDR-3 memory . The first card already appeared in Japan for approximately $185, the card default frequencies are 600/1500/1800 MHz. Gigabyte mentions about the use of 65 nm g92 video chip , but in this case on the video card box it is possible to reveal a notification about the support to hybrid power technology . This once more proves, that this function is not attached to 55 nm g92b Chip.

The main advantage of this card is the high-quality cooler form zalman production . There are no radiators on the memory microcircuits

Nvidia's plan to shift from 65nm to 55nm to lower costs is baring fruit and we have the first 9800 GT 55nm in our hands. The biggest difference compared to the 65nm verison is its support for HybridPower technology that is not included on 65nm based 9800 GT cards.

The new core is revision B and it has a smaller die size (55nm - ca. 270mm2 ) compared to revision A (65nm - ca. 330mm2).

:)

During the die shrink on the G92 from 65nm to 55nm nothing in terms of architecture was changed. We still have 112 stream procesors with 16 ROPs. Actually the Geforce 9800 GT is identical to the Geforce 8800 GT, it has the same specifications except HybridPower support on 9800 GT 55nm cards.

We showed you Sparkle's passively cooled 9800 GT card here, but what we did not know at that time is that it was based on 55nm GPU.

We ran GPU-Z and it displayed the specs showing us that Sparkle's card is based on the old 65nm GPU. Later on, we found more time to play with the Sparkle's 9800 GT card, and after we took the cooler off, we saw the 55nm GPU behind.

We have a nice picture where you can see it is physically smaller than previous revision A chip. The one with the blue PCB is Sparkle's 9800 GT, and below you can see an 8800 GT.

Although it's anything but expected, HIS seems to be one of the first of AMD's partners after Sapphire and PowerColor to have finished off its own in-house Radeon HD 4850 design with the the addition of an IceQ 4 heatpipe cooler on it.

HIS has gone for a blue PCB and the IceQ 4 cooler means that we're looking at a dual slot design. Although this is unlikely to cause any problems for most, it's a shame that a better single slot cooling solution couldn't be made. The new cooler should at least run quieter than the reference cooler.

The card will have 512MB of GDDR3 memory, but no other specification details were revealed, although we'd expect these cards to be clocked faster than the reference designs. As with previous HIS designs, this card will feature gold plated DVI connectors and HIS is bundling a DVI to HDMI adaptor with the card

mr pc جان با این مطلب مشخصه که دارن کم کم روی 4850 به نحوهای مختلفی مانور میکنن و مطمئنا بهتر از اینها هم خواهد شد . الان هر چی موجود توی بازار هستش با همون فن ساخته شده ATI هستش ولی تا چند وقت دیگه همه چیز مثل کارتهای دیگه تغییر میکنه .

درود

جناب حسینی همونطور که در اخبار قبلی که قرار داده بودم ذکر شده بود و شما هم فرمودید معلوم هست که طبق روال گذشته کمپانی های مختلف دارند به نحو های گوناگون روی این کارت های جدید تغیراتی رو ایجاد میکنند و چه ار لحاظ سیستم کولینگ و چه از لحاظ کلاک کاری این کارتها در جهت بالا بردن کارایی این کارتها ایجاد میکنند تا فاصله بیشتری رو از لحاظ کارایی با برد مرجع داشته باشند و سهم بیشتری از بازار رو به محصولاتشون اختصاص بدهند.جالب اینجاست که کارتهای 9800 و 9500 جی تی که مدت بسیار کمی از تولیدشون میگذره هم از سوی بعضی از کمپانی ها از همین بدو تولید با کولرهای غیر رفرنس ارایه شدند که اخبارشون در صفحات قبل قرار دارد.

After the success of its RV770 and refreshed DirectX 10.1 cards ATI wants to continue its winning streak with a DirectX 11 card.

We still don’t know the codename, but let's assume that the next generation performance / mainstream chip is codenamed RV870. This chip will likely have DirectX 11 support; at least this is what our sources believe at this time.

There is an important indication that RV870 might launch before DirectX 11 becomes available but this can only be a good thing for ATI, but if we were betting people we would suggest that such a chip should be available a year from now, in late Q2 or early Q3 2009.

AMD/ATI recently introduced the Radeon HD 4800 line-up of graphics cards, featuring the 55nm RV770 core. The cards have only just become available, but there are a lot of rumors on the RV770's successor already. It's been known for a while that the RV870 would be a die-shrink of the RV770, in other words, a smaller production process with the same architecture. AMD/ATI has now announced that the smaller process will be the 40nm one.

The 40nm RV870 3D-chip is codenamed Lil Dragon, AMD/ATI claims twice the performance-per-Watt compared to the RV770. Lil Dragon would be about 20% faster than it's predecessor, while maintaining a lower power consumption. It's rumored that the RV870 chip will feature 960 stream processors, the current RV770 has 800 of those.

HIS has officially launched its latest addition to the IceQ lineup of graphics cards, the HIS HD 4850 IceQ4 card. Unfortunately, the card is still working at reference clocks, 625MHz for the core and 1,986MHz for 512MB of GDDR3 memory. On the other hand, you do get a card that will certainly be less hot and less noisy than the reference one.

The card is cooled by the fourth generation of the IceQ cooling. According to the press release, the new IceQ cooling should bring increased cooling capacity of up to 20 percent under load. As it was the case with previous IceQ cooling series, this one also transforms the card to a dual slot solution with the ability to push the hot air out of the case.

The card is not yet available in Europe but we will keep our eye out as we hope that the price will not be much higher when compared to the reference cooled cards.

According to our associate, on 12 August AMD will officially release the 3d- accelerator ATI radeon HD 4870 X2. The recommended price of this card is equal to $499.

Due to the high price of GDDR5 memory , the difference between ATI radeon HD 4870 and ATI radeon HD 4870 X2 will compose $200. to fill the empty interval between these products , AMD will release the accelerator ATI radeon HD 4850 X2, which will be equipped with GDDR3 memory . The application of GDDR3 memory will allow to set the price of ATI radeon HD 4850 X2 in the range $399-449.
