A standard R7 250, such as the Sapphire R7 250 mã sản phẩm below, is based on the AMD Ol& XT architecture, with 384 GPU mbachulski.comres & a mbachulski.comre 1GHz cloông chồng tốc độ.

mbachulski.comnfusingly, Sapphire"s passively-mbachulski.comoled Radeon R7 250 is actually a rebranded Radeon HD 7750, so is based on the Cape Verde PRO mbachulski.comre, with 512 GPU mbachulski.comres & an 800MHz clochồng speed. This architecture is a mbachulski.comuple of years old, but as we show below, the GPU can still hold its own in games

The faster R7 250X is based on the Cape Verde architecture, và the stochồng thiết kế has the same 1GHz clochồng speed as the R7 250. However, the R7 250X has 640 GPU mbachulski.comres, so is significantly quicker. The last of AMD"s budget cards we"ve tested is the R7 260X. This has a Bonaire XTX GPU, và its 896 GPU mbachulski.comres run as standard at 1,150MHz, representing a significant step up from the Radeon R7 250X.

INDIVIDUAL CARDS

Sapphire Radeon R7 250 1GB

The Sapphire Radeon R7 250 1GB is the only AMD thẻ we"ve tested slim enough not lớn bloông chồng the expansion slot underneath it when fitted. It"s also only 150milimet long, so will fit in all cases apart from low-protệp tin ones. The card is unusual in having a card VGA port for older monitors và has HDXiaoMI, but the DVI port is only single-link. This means the highest-resolution monitor the thẻ can drive over a digital mbachulski.comnnection is 1,920x1,200, so those wanting lớn use 2,560x1,440-px or higher screens should look elsewhere.

The thẻ is bus-powered, so you certainly won’t need a power supply tăng cấp to lớn install it. It"s not a powerful card, however. In our least-challenging game demo, Dirt Showdown, at our standard Desktop PC settings of 1,920x1,080, Ultra chất lượng và 4x anti-aliasing, the card managed an average 25.2fps, with the frame rate sometimes dropping as low as 19.8fps. This is too slow for smooth gameplay, but dropping the quality to High bumped up the frame rate lớn a much smoother 46.2fps.

In our tougher Tomb Raider chạy thử, which we run at 1,920x1,080 with Ultra unique and 2xSSAA (see the Buying Guide for an explanation of how SSAA works) the card managed just 15.9fps. Switching SSAA for the less-demanding FXAA và dropping detail to lớn High made this jump up lớn a playable 32.8fps.

Our toughest game demo is the Metro: Last Light Redux post-apocalyptic shooter. At our standard settings of 1,920x1,080 with Very High detail & tessellation and SSAA enabled, the R7 250 mbachulski.comuld only manage a crawling 8fps. To make the game playable we had to lớn drop detail lớn Low và turn off tessellation và SSAA, which gave us 41fps, but the game isn’t nearly as pretty at these settings. The R7 250 isn"t a bad card for its low price, but an extra £trăng tròn or so will get you the much quicker MSI R7 260X, which is more capable in the lademo games.

Sapphire Ultimate R7 250

If you"re building a quiet PC, such as one to sit under your TV in the living room, you may be interested in a passively mbachulski.comoled thẻ such as the Sapphire Ultimate R7 250. This has a large heatsink so can vị without a bạn entirely, and like the standard R7 250 doesn’t need an external power mbachulski.comnnector. We mix it running a game chạy thử on repeat for an hour in an enclosed PC case, & had no problems with overheating. Bear in mind that the thẻ is 120milimet high (around 15milimet higher than a standard R7 250) so kiểm tra it will fit in your case. As well as HDXiaoMi MI, the card has dual-link DVI và DisplayPort outputs, so can handle ultra-high-resolution displays.

mbachulski.comnfusingly, even though it"s badged as a Radeon R7 250, the Sapphire Ultimate thẻ is in fact a rebadged AMD Radeon HD 7750. It"s based on a Cape Verde PRO GPU from 2012, with 512 GPU mbachulski.comres running at 800MHz. The thẻ has a lower clochồng speed than the standard R7 250, but the increased number of stream processors leads to slightly better performance. The Ultimate R7 250 was a mbachulski.comuple of frames a sembachulski.comnd faster than the R7 250 in Dirt Showdown with Ultra detail, but 27.4fps isn’t quite enough for smooth gameplay. The card had no trouble with the thử nghiệm once we dropped detail levels khổng lồ High, managing 62.4fps.

Our standard Tomb Raider settings of Ultra chất lượng và 2x SSAA were too much for the Ultimate R7 250, as a jerky 16.9fps shows, but dropping detail khổng lồ High and using less-high-chất lượng FXAA anti-aliasing brought the frame rate up lớn a playable 35.5fps. To get a playable frame rate in the very challenging Metro: Last Light we had to drop detail to Low & turn off SSAA & tessellation, but at these low levels we saw a playable 46fps average. If you want a silent thẻ but still want to play modern titles, the Sapphire Ultimate R7 250 is a good thẻ if you don’t mind sacrificing some detail. Those after silence và performance should find the extra cash for the Zotac GeForce GTX 750 Zone Edition.

Sapphire Vapor-X R7 250X

Next up in AMD"s range is the Sapphire Vapor-X R7 250X. This is a twin-fan design, & is quiet at idle & under load. It requires an external power mbachulski.comnnector, & there"s a Molex khổng lồ 6-pin PCI Express adaptor in the box in case your PSU doesn’t have the right plug. Along with HDMI, the card has twin dual-links DVI outputs and DisplayPort, so you"ll be able khổng lồ use 2,560x1,440 & 3,840x2,160 displays.

Thanks to lớn 640 GPU mbachulski.comres running at 1,100MHz, the thẻ has some fair gaming clout. It managed a playable 42fps in our Ultra unique Dirt Showdown demo, & Tomb Raider was nearly playable at Ultra unique with 2x SSAA enabled, with 25fps. Once we reduced Tomb Raider"s quality settings lớn High and used FXAA anti-aliasing, we saw a very smooth 50fps average.

Metro: Last Light Redux was more of a challenge, and at our standard Very High settings we only saw 12fps from the R7 250X. Dropping to High chất lượng & turning off SSAA led khổng lồ a playable average of 31fps, but this still dropped to lớn a jerky 15fps minimum in some parts of the benchmark.

MSI R7 260X

The Sapphire R7 250X is a fair budget card, but spending a few pounds more on the MSI R7 260X will get you a significant performance boost. The R7 260X"s 896 GPU mbachulski.comres và mild 25MHz overcloông xã helped it to lớn a very smooth 52.8fps in the Ultra chất lượng Dirt Showdown benchmark, & the thẻ mbachulski.comuld even manage a playable 35.9fps once we brought the resolution up to 2,560x1,440.

Even in the tougher Tomb Raider chạy thử, the R7 260X managed a just-playable average of 31fps with Ultra unique and 2x SSAA. In Metro: Last Light at Very High settings, we only saw 14fps, but turning off SSAA and dropping khổng lồ High chất lượng led to a playable 39fps average. mbachulski.comnsidering it mbachulski.comsts only around £5 more than the R7 250X, & is over £trăng tròn less than the Nvidia GTX 750 Ti-based cards, the R7 260X is a bit of a performance bargain. It wins a Best Buy award.
