#SiliconHistory post One of the most overlooked pieces of silicon in the 7th generation was the #Xbox360 Xenon CPU’s VMX128 SIMD unit. While the #PS3 Cell excelled at high throughput data parallel workloads through its #SPEs, the #box360 #Xenon was not merely a generic #PowerPC CPU. Its VMX128 #SIMD extension was a game-focused enhancement of PowerPC VMX/AltiVec, adding a larger vector register file and specialized instructions that mapped unusually well to common game-engine math workloads, especially vector dot products, transforms, animation, physics, culling, and other linear-algebra-heavy code. Arguably, Xenon’s strongest capability was performing a Vector3 dot product per cycle together while avoiding the extra w component of a Vector4. That is something very few modern CPUs can do as directly for this specific operation. This instruction set gave the #Xbox 360’s Xenon a major advantage. In dot-heavy arithmetic workloads, it would realistically outperform top-of-the-line 2005 #PC CPUs like #Intel Pentium EE 840 and #AMD Athlon 64 X2 4800+ by roughly 2.7× to 6.7× in raw arithmetic capability. Those high-end PC chips had no equivalent #SSE dot-product instruction. Their SIMD paths had to construct the same result through a sequence of vector multiplies, shuffles, horizontal additions, and broadcasts. That mattered because dot products are everywhere in game engines: transforms, 3D rendering, skeletal animation, #physics constraints, collision detection, frustum culling, lighting calculations, projections, pathfinding, and plane tests. However, Xenon, as an in-order CPU, was not as strong in branch heavy code, pointer-heavy code, or code that was not cache friendly by nature. For the mathematics at the heart of a 2005 game engine, VMX128 gave the Xbox 360 capabilities that desktop CPUs would not match as directly until later SIMD extensions arrived and general transistor counts increased. https://t.co/tuOFxt2dNN #Xbox #Xbox360 #Xenon #VMX128 #SIMD #GameDev #GameEngine #GraphicsProgramming #Cpp #CPU #Intel #AMD #RetroHardware #math #screenshotsaturday

Saw Xbox 360 trending... I thought something had happened to it, very relieved to figure out that it's healthy and doing well #Box360

Wet on #box360 starring Rubi Malone. An action game that combines shooting, swordplay, acrobatics and gore. Music and slow motion fight scenes help create a cinematic “Kill Bill” style experience. #xboxsunday #sundayonxbox #shareyourgames
