iPhone 4G to Get New Graphics Chip? Imagination Technologies Announces new PowerVR SGX545 Mobile GPU
name to talk about the next-generation or fourth-generation iPhone due
this June or July. Then it hit me! The awesomeness of this iPhone name
is simply awesome! Imagine Apple naming the next iPhone the iPhone 4G
for two reasons! Not only is it the fourth-generation iPhone but it
could also support 4G connectivity. Catch my drift?Despite the fact that
a Verizon-bound LTE iPhone has been rumored before, we re not going to
analyze that rumor today. We have something more interesting for you, a
brand new mobile GPU from Imagination Technologies. The graphic chip
maker has unveiled its new PowerVR SGX545 mobile GPU which is probably
going to equip the iPhone 4G.
Here s the full list of features of the PowerVR SGX545:DirectX10.1 API
support Enhanced support for DirectX10 Geometry Shaders DirectX10 Data
assembler support (Vertex, primitive and instance ID generation) Render
target resource array support Full arbitrary non power of two texture
support Full filtering support for F16 texture types Support for all
DirectX10 mandated texture formats Sampling from unresolved MSAA
surfaces Support for Gamma on output pixels Order dependent coverage
based AA (anti-aliased lines) Enhanced line rasterisation
Besides full profile OpenCL 1.0 and OpenGL 3.2 support the new GPU will
offer a bunch of extra features:Support of round-to-nearest for
floating-point math Full 32-bit integer support (includes add, multiply
and divide) 64-bit integer emulation 3D texture support Support for the
maximum 2D and 3D image sizes specified in the full profile.
Like always, we can t confirm that the iPhone 4G will have this specific
GPU on board but it s only logic to assume that Apple s next phone will
offer better graphics than the previous models. After all Apple needs an
excuse to convince us to buy more games and video shows from the iTunes
store once we have the iPhone 4G in our hands.
Oh, and did I tell you that �iPhone 4G � is a really cool name for a
device that doesn t exist yet?
