widescreen display at the same resolution as the first generation. Due to the use of a mobile processor, this laptop was thinner and lighter than most other high performance gaming notebooks of its time. It has a design very similar to the XPS M1710. It was initially given the Nvidia GeForce 256 MiB 6800 Ultra Go GPU which was a Dell exclusive at the time. The laptop was rebranded as XPS M170 soon after the GeForce Go 7800 GTX was incorporated. The Inspiron 9300 was based on it, being substantially the same laptop with an ATI Mobility Radeon X300 in the base model. XPS M140 (Late 2005) – The lower end model XPS computer that has a chassis identical to a Dell Inspiron E1405 laptop. This model features a choice of several Intel mobile processors, 14.1-inch widescreen and between 512 MiB to 2 GiB of RAM. This model being more media-oriented than gaming currently does not feature a dedicated graphics card. This model has been replaced by the E1405, a 14.1-inch laptop physically similar the M140. It features the newer Intel Core Duo processors and Intel's 945 chipset. It is no longer classified as an XPS laptop, however. Gen 1 Inspiron XPS – The first XPS laptop, which was a rebranded Inspiron 9100, was a very heavy desktop-replacement laptop starting at 9.06 pounds without power supply (which added an additional 2.5 pounds). This was because it was offered with either a 3.4 GHz desktop Pentium 4 HT "Prescott" processor, or the 3.4 GHz "Gallatin" Pentium 4 Extreme Edition processor at the same clock speed, which gave off tremendous amounts of heat due to their high clock speeds and inefficient microarchitecture, despite a very large copper-based heatsink that spanned the width of the unit with three fans. Other features included a 1920×1200 15.4-inch LCD, and subwoofer integrated into the bottom of the battery casing, with the 12-cell battery (the 16-cell battery does not include a subwoofer.) Earlier models came with an ATI Mobility Radeon 9700 with 128 MB of memory, and later models with the Mobility Radeon 9800 with 256 MB of memory. The Mobility Radeon 9800 was based on the R420 core, the same as early ATI Radeon X700 and X800 desktop graphics cards, but with half the pixel pipelines disconnected. A popular modification to the GPU was to bridge two traces in the top right corner of the PCB
