Core Viewpoint - The article discusses the significant update of the "TinyGPU" v2.0, a minimal GPU designed by Pongsagon Vichit, which is capable of rasterization, transformation, and lighting processing, similar to the GeForce 256 [2][5]. Group 1: Technical Specifications - TinyGPU v2.0 utilizes approximately 200,000 transistors and is designed for a maximum tile size of 4x4 [2]. - The performance of TinyGPU v2.0 is limited to a frame rate of 7.5 to 15 fps at a resolution of 320 x 240 pixels or lower, using a color depth of 4 bits [5]. - The GPU supports up to 1,000 triangles, backface culling, and features like dynamic directional lighting and flat shading [5][10]. Group 2: Comparison with Previous Versions - The first generation of TinyGPU could only support two polygons and achieved a frame rate of up to 60 fps at a resolution of 640 x 480 pixels with a 6-bit color depth [6]. - The advancements in TinyGPU v2.0 are notable compared to its predecessor, which had significantly lower capabilities [3][6]. Group 3: Production and Cost - TinyGPU v2.0 has been submitted for production through Tiny Tapeout, with an estimated cost of around $1,500 for the maximum allowed design of 16 tiles [6]. - The design includes two texture ROM images and utilizes a clock frequency of 50 MHz [10].
