Xtremesystems.org论坛的guess2098拿到了一块帝盟的Radeon HD 4870 X2样品，重点考察了其超频性能。

帝盟这块卡与昨天德国PCGHX.com测试的一样，也是第二修订版本，都采用了来自海力士的GDDR5显存，而之前参与预览测试的第一批样品用的都是奇梦达GDDR5显存。据悉，显卡厂商可自行决定采用哪家的显存，但很显然，二者的超频能力会有所差异。

guess2098对这块4870 X2样卡的BIOS做了一些更改，最终将核心/显存频率由默认的750/3600MHz超到了850/4000MHz，同时电压加到1.45V。据称奇梦达GDDR5显存可以轻松超至4800MHz，看来海力士的还是略差一些。

参与测试的其他硬件还有：Intel Core 2 Extreme QX9650 OC 4.45GHz四核心处理器、华硕玩家国度Rampage Formula X48主板、G.Skill F2-9600CL5D-4GBPI 2×2GB内存、S.Skill SATA 32GB固态硬盘、Tt 1200W电源。3DMark2001SE/03/05/06ndows XP下测试，3DMark Vantage则在Windows Vista下进行。

3DMark2001SE：85558

3DMark03：84805

3DMark05：29741

3DMark06：25126

3DMark Vantage：E35356

3DMark Vantage：P16865

3DMark Vantage：X8037

作为对比，以下是Radeon HD 4870 CrossFire的3DMark03成绩。考虑到平台差异，可以看出Radeon HD 4870 X2的双芯效率还是很不错的。
