LINK (Guru3D)unsure of the source for this, Guru3D cites a forum member but that could be anyone really. anyway, posting this in case anyone is interested

Graphics:
Custom AMD RV770 Chip “WOLF” @ 766Mhz on 32nm process
1398 Gflops <- according to
Wikipedia, this puts it just above the Radeon HD4890 in terms of compute power
CPU:
Custom IBM Power 6 Chip “FOX” on 32nm process
4 cores, each two way SMT-capable and clocked at 3.5 GHz
175.9 GFLOPS theoretical peak performance (single-precision) <- cant find any concrete comparison numbers for this, but my Core2 e8400 @ 4GHz gets 26GFLOPS in IntelBurnTest
87.6 GFLOPS theoretical peak performance (double-precision)
Memory:
512 MB XDR2 DRAM main memory
+ 1024 GDDR5 video memory <- comparable to brand new midrange cards, such as the GTX560 Ti and some HD 6950 variants
+ 16 MB eDRAM
Storage:
2.5-inch SATA hard drive with 250 GB / 320 GB capacity
Expanded storage via SD and SDHC card memory (up to 64 GB)
Media:
Custom Blu-ray Disc, up to 50 GB
Compatible with 7 cm Nintendo GameCube Game Disc and 12 cm Wii Optical Disc <- could possibly render older games at higher resolutions?
Display:
Video output formats
Composite video: 480i, 576i (PAL)
S-Video: 480i, 576i (PAL)
RGB SCART: 480i, 576i (PAL)
Component (YPBPR): 480i, 576i (PAL), 480p, 576p, 720p, 1080i, 1080p
D-Terminal: 480i (D1), 480p (D2), 720p (D4), 1080i (D3), 1080p (D5)
HDMI: 480p, 576p, 720p, 1080i, 1080p
