English to Chinese Tech/Engineering IT (Information Technology) Bulldozer processor

At the higher end of our tests, the FX-8150 takes something like a lead, but doesn’t pull away much further than the Core i5-2500K managed to when we tested Crysis 2.
试译：
在测试的较高端部分，FX-8150的性能要领先，但是其优势比我们测试《孤岛危机2》时酷睿i5-2500K的性能大不了多少。

说明：这是在用基准测试程序来评比AMD的FX-8150 和英特尔的Core i5-2500K 这两款处理器在游戏方面的性能。

这整句话都没明白，到底是啥意思。
何谓At the higher end of our tests？ takes something like a lead又是啥意思，后半句同样看得稀里糊涂。
