(Click to view enlarged picture)
The locations of each component are
very simple. no feature on yellow PCB. impressive component is strong
thermal epoxy between chip and cooler. samsung's 6ns memory
posintioned on PCB. but they don't support TV-out or TWIN-VIEW.
support only D-SUB. i have nothing to say about layout
This product is only for user don't
need additional feature. that's why composition is simple.
KYRO chip

After removing clooer, KYRO chip
showed. to explain Specification of KYRO i made a table as follow.
Compared object is GeForce2 MX.

Specification of KYRO is lower than
nVIDIA's value chipset, GeForce2 MX's. nobody can expect KYRO's
performance will be better than GeForce2 MX. but ATI's RADEON that
lower than GeForce2 MX on specification show the powerful performance
compared to GeForce2 MX in some part.
also. not shown on the above table.
KYRO's core and memory clock are same 115MHz. it's a low memory
frequency even though adapted samsung's 6ns memory. it's a lowest
memory frequency among peripherals announced in 2000. you can imagine
it can be overclocked because memory's frequency is very low.but core
frequency must be synchronized with memory frequency. core clock also
overclocked when you overclcoked only memory. chip emit high storm of
heat when overclocked core or memory. so i abandon to do overclock
You need to pay attention to Z-buffer
tile render structure. this technology is similar with voodoo 4's
VSA-100's HSR. nobody can ignore STM's technology power as a they
applied this technology to their first card.
Tile Render means calculating only visible things. 3D including X,
Y, Z. generally nobody can watch thing that Z calculated. Z is only
tools that measure an interval. normally 3D graphic card that not
support Tile Render has calculated Z. because of this problem. the
graphic cards are used to waste a memory and bandwidth. KYRO will show
better performance than GeForce2 MX if this technology properly
applied
another attention is supporting Environment Bump Mapping. i pointed
out last ATI RADEON's review. the graphic cards that support
Environment Bump Mapping are only matrox G400/450 and RADEON series.
but we should add KYRO in the list. KYRO also support Environment Bump
Mapping.

Supporting Environment Bump Mapping doesn't
mean all of 3D. but i have confidence that the graphic card support
Environment Bump Mapping will be produced a lot and game aldo support.
there are some fault. it 's a heat. KYRO runs
just 115MHz but it emits a lot of heat. i decribed above, i can't do
overclocked because of storm of heat. second fault is depending on
CPU. it 's why KYRO does not support T&L. if you have powerful
CPU(at least Athlon 1GHz) KYRO show you satifactory performance |
