The impact of the iPhone 3GS RAM increase

The most significant thing that Apple’s been touting about new iPhone 3GS is its speed. Generally, when you think about speed improvements, you think of faster CPUs, faster GPUs, and such. But one very important difference in the 3GS that’s contributing to the overall performance is the increased RAM and that’s pretty much gone under the radar.

[…]

CPU (central processing unit):

  • original iPhone: ARM 11, 412 MHz
  • iPhone 3G: ARM 11, 412 MHz
  • iPhone 3GS: ARM Cortex, 600 MHz

GPU (graphics processing unit):

  • original iPhone: PowerVR MBX Lite
  • iPhone 3G: PowerVR MBX Lite
  • iPhone 3GS: PowerVR SGX

RAM (random access memory):

  • original iPhone: 128 MB
  • iPhone 3G: 128 MB
  • iPhone 3GS:256 MB

via tap tap tap ~ 256÷128=10?! The impact of the iPhone 3GS RAM increase.

Just goes to show, once again, that you can ALWAYS do with more RAM, regardless of whether you’re upgrading a computer or an iPhone – especially when you’re doubling the original amount of RAM to begin with.

iPhone 3G S Specs Revealed

T-Mobile.nl has posted some technical specs about the iPhone 3G S revealing that the newest iPhone carries a 600 MHz processor and 256MB of RAM. A nice bump in processor power from the iPhone 3G.

The iPhone 3G had a 412mhz processor while the iPod Touch had a 532mhz processor, until now, the 2nd generation iPod Touch was the fastest device by a good margin on the lineup but the iPhone 3G S has changed that. […] The processor/ram information seems to confirm many details that were first revealed in a Chinese forum post.

The new iPhone is also believed to use the new PowerVR SGX graphics processing unit which provides support for OpenGL ES 2.0. This notably improved performance may require developers to support these multiple device capabilities within their apps.

MacBook: White substance on memory cards or slots

White Substance Image

The white substance is a high-quality lubricant used by factories to facilitate installation of memory DIMMs. The grease will not damage the memory or any MacBook components.

Over time the lubricant may evaporate and become less visible. Future RAM installations will not require additional lubricant.

Note: While the grease presents no potential harm if it contacts your skin, it should be washed off using soap and warm water.
