Sapphire 6850 Vapor-X Testing Test Rig CPU: Phenom II 1090T @4.2GHz Motherboard: Gigabyte 990FXA-UD7 RAM: G Skill Ripjaw 1600 7-7-7-24 4gb Storage: Seagate Baracuda 7200.12 500GB PSU: Coolermaster Silent Pro 850W Case: Corsair 700D The driver used for testing was CCC 11.10. Methodology For graphics card testing, here at XSReviews our aim is to provide a set of clean, reliable benchmarks. For each test, the test was repeated three times and then an average taken or where results were inconsistent, tests were continued until two concordant results were reached. The benchmarks consist of a mixture of games and synthetic benchmarks; games testing is carried out through a specifically designed benchmark suite for that particular title or by using a time demo and the utility FRAPS to record the frame rates. The following software was used in the testing of the graphics cards: - 3Dmark 11 - 3Dmark Vantage - 3Dmark 06 - Furmark – for temperature testing - Unique Heaven - DIRT 3 - Crysis Warhead Overclocking and Thermals The Sapphire 6850 Vapour-X was a joy to overclock. I used Sapphire Trixx to overclock the card and tested stability using Furmark. After around 20 minutes of tweaking, I found that 1060MHz on the core, with 1.25V was the highest stable clock I could achieve. The Vapour-X cooler did a great job. Running at stock speeds the GPU sat at 38C at idle and 68C under load. While overclocked the GPU only hit 74C which is well within the thermal limits of the core. Throughout the tests the fan stayed very quiet and only became slightly audible under overclocked load.

A Radeon 6870 IceQX Tástáil Rig Tástáil Míle buíochas do CryoPC as an rig tástála seo a leanas: LAP: Core i5 750 @ 4GHz Motherboard: Asus P7P55D-E RAM: Corsair Dominator 4GB PC3-12800 DDR3 Stóráil: Samsung F3 16MB 500GB PSU: Corsair TX 650w CÁS: Hades NZXT Modheolaíocht Chun tástáil cárta grafaicí, anseo ag XSReviews ár n-aidhm a chur ar fáil sraith de, tagarmharcanna glan iontaofa. I gcás gach tástála, a bhí arís agus arís eile ar an tástáil trí huaire agus ansin ar an meán a rinneadh nó atá ina torthaí neamh-chomhsheasmhach, Leanadh tástálacha go dtí go raibh bainte amach dhá thoradh concordant. Is éard atá sna tagarmharcanna meascán de cluichí agus tagarmharcanna sintéiseacha; Tá cluichí 'tástáil i gcrích trí seomraí atá deartha go sonrach thagarmharc don teideal ar leith nó trí úsáid a bhaint taispeána am agus an FRAPS fóntais a thaifeadadh ar na rátaí fhráma. Baineadh úsáid as an bogearraí seo a leanas i dtástáil na cártaí grafaicí: - 3Dmark 11 - 3Dmark Vantage - Furmark - Heaven uathúil - Crysis warhead - STALKER: Sky Gréine - Dawn an Dara Cogadh Gach ceann de na tagarmharcanna, go háirithe na cluichí, a úsáid trí / ceithre shuíomh gach a ceapadh chun cur le réimse amháin faoi leith ionas go a thabhairt ar dhul chun cinn líneach. Dá bhrí sin, is féidir comparáidí a dhéanamh, ní hamháin idir cártaí éagsúla ach freisin ar fud coigeartuithe suímh ar leith; mar shampla, choinnigh an Difríochtaí maidir le ráta fráma idir rúin éagsúla le gach suíomh eile mar an gcéanna.
