GMA X4500 The GMA X4500 and the GMA X4500HD for desktop[14] were launched in June 2008.[15] The GMA X4500 is used in the G43 chipset[16] and the GMA X4500HD is used in the G45 chipset.[14] The GMA X4500 is also used in the G41 chipset,[17] which was released in September 2008.[18] The GMA 4500MHD for laptops was launched on July 16, 2008. Featurewise, the 4500MHD is identical to its desktop cousin, the X4500HD.[citation needed] It had been previously rumored that a cost-reduced version, the GMA 4500, was to be launched in late 2008 or early 2009[19] and was to be used in the upcoming Q43 and Q45 chipsets.[17] But in practice the Q43 and Q45 Chipsets also use the GMA X4500.[20] The difference between the GMA X4500 and the GMA X4500HD is that the GMA X4500HD is capable of "full 1080p high-definition video playback, including Blu-ray disc movies",[14][21] Like the X3500, X4500 supports DirectX 10 and Shader Model 4.0 features. Intel designed the GMA X4500 to be 200% faster than the GMA 3100 (G33 chipset) in 3DMark06 performance[22] and 70% faster than the GMA X3500 (G35 chipset) http://en.wikipedia.org/wiki/Intel_GMA#GMA_X4500
