IPhone 3G S Gets Taken Apart, CPU And RAM Revealed Mp3 Download
Apple were quite keen on emphasizing that the recent iPhone 3G S was twice as quick as the original iPhone 3G the other day, but they never mentioned the actual specs of the chipset. Luckily details are starting to appear now and it gets clear that the iPhone 3G S packs a powerful 600 Mega Hertz (MHz) ARM Cortex A8 Central Processing Units (CPU) and a PowerVR SGX graphics accelerator.
Providing a worthy hardware upgrade over the 412 Mega Hertz (MHz) Central Processing Units (CPU) of the iPhone 3G, the 3G S also packs double the Random-Access Memory (RAM) of its predecessor (256Mega Bytes (MB) compared to 128Mega Bytes (MB) on iPhone 3G). Also the Central Processing Units (CPU) of the iPhone has received upgrades in more than just speed. The recent core manufacturing process is now 65nm instead of 90nm and has put on more L1 cache, bringing along some L2 cache as well.
The iPhone 3G S comes with double the L1 cache of its predecessor and also introduces 256Kilo Bytes (KB) of L2 cache, which isn't supported by the ARM11 Central Processing Units (CPU) of the previous gen iPhones. The GPU has been upgraded too and now the iPhone 3G S comes with PowerVR SGX instead of the much toned down PowerVR MBX-Lite. This accelerator can theoretically give some 600% increase in geometry performance and a 150% increased fill rate.
Unfortunately, the lower specs create the original iPhone 3G unable to support the OpenGL ES 2.0 graphics API, which will come with the iPhone 3G S. That will give the developers a headache as they have to create their apps support OpenGL ES 1.1 and OpenGL ES 2.0 if they want to acquire better performance on the iPhone 3G S and backwards compatibility with the original iPhone 3G.
