Pros: 2 mini display port 1.2 (using both)Ģ dvi, 1 single link and 1 dual link (using both) A GTX 460 almost draws 100Watts more at load than this card, and has comparable performance. Overall Review: It has much less power draw for its performance than its competitors, and only requires 1 PCI-E power connector, where most of Nvidia's require 2. But I don't consider this a con, it leaves lots of headroom.
Just to see how loud it would get I manually ran it at 100%, because it will never get to 100% unless the temps are 90C+.
CF ready.Ĭons: The fan at 50% or over is noticeable, but not annoying. This not only yields 10fps more in games, but it still wont get above 70C. I got core/memory clocks from 775/1000 respectively, to 940/1025 respectively, without even changing the voltage. Very low power draw in comparison for the performance it delivers. After re-application of better thermal paste, even with 3dMark, it will never go above 70C. Can Play BF3 with all settings on "Ultra". Radeon HD 5850 cards now cost around £250 (inc VAT) which is a significant leap up from the £215 (inc VAT) price we saw in our last Buyer's Guide.Learn more about the XFX HD-685X-ZCFC Model BrandĪMD Advanced Parallel Processing Technology (APP)įorm Factor & Dimensions Card Dimensions (L x H)Īdditional Information Date First Available However, it seems that ATI has hiked the price of the HD 5850 up to accommodate the HD 5830 at this price. The final note before heading into the test results is the price of this new card - we'd expected a price of around £160-180 inc VAT, so the £200+ prices are a surprise. Whether this will be the case with the HD 5830 remains to be seen, but the GPU tag of “Cypress LE” doesn’t bode too well – limited edition anyone? However, cards based on the HD 4830 GPU dried up fairly quickly, likely due to improved manufacturing processes and higher yields of HD 4850- and HD 4870-class chips. This card filled a similar gap in the HD 4000-series range with a great degree of success - hitting an attractive price-performance sweet-spot. While the idea of a card to fill the performance gap between the HD 5850 and HD 5770 is a sound one, there's a slight concern based on our experience with the Radeon HD 4830. Interestingly though, as the HD 5830 is based on a higher clocked version of the Cypress GPU than the HD 5850, peak power consumption is actually second only to the HD 5870 at 175W. The result is a card that, on paper at least, sits almost exactly in between the HD 5770 and HD 5850 when it comes to performance, although in some aspects like pixel fill rate, it’s actually a little behind the HD 5770. If you look at the cards above, most seem to take the same route, apart from the tiny XFX.Click to enlarge The card ATI sent us to test with was based on an old HD 5870 board, and it looks identical. The clock speeds of the HD 5830 are also something of a mish-mash between those of the HD 5770 and HD 5850 either, with a GPU clock of 800MHz (75MHz more than the HD 5850 and 50MHz less than the HD 5770), and a memory clock of 1GHz (4GHz effective). The number of ROPs has been cut to just 16, in line with the HD 5700-series, but half that of the HD 5800-series the HD 5830 does retain the 256-bit memory bus of the its bigger brothers though, allowing the HD 5830 to match the memory bandwidth of a HD 5850 at 128GB/sec.
The limitations go a fair bit further than just the stream processor count, too. This means the HD 5830 offers a shader count of 1,120 (with 56 texture units) in comparison to the HD 5850’s 1,440 (with 72 texture units) and the HD 5870’s 1,600 (with 80 texture units). This somewhat odd approach is because the Cypress GPUs in question (dubbed Cypress LE) are those that didn’t quite make the cut to become HD 5870s, HD 5850s or HD 5970s, but which still have sufficient functional parts to churn out a few million pixels per second Our review sample is simply an HD 5830 GPU and accompanying memory fitted to an HD 5870 reference card, and, as you can see above, there's a lot of variety between different partner cards. The HD 5850 is somewhat unique though in the fact that there will be no 'reference' or stock design for the card, with ATI selling the GPUs to board partners who then add their own power delivery circuitry, cooling and PCBs for their own individual take on the HD 5830. From left to right: XFX, Sapphire, Asus, MSI, HIS. There's no reference card design for the Radon HD 5830, so everyone's got a different design.
