叙事 (narrative) (6)
- 2026-07-03 · pin count vs HBM4
slashing the pin count to 1/5th
tags: 好数字·好观点 · → daily
value: qty=1/5 · direction=less
- 2026-07-03 · signal speed
quadrupling signal speeds to 32 Gbps
tags: 好数字·好观点 · → daily
value: qty=32 Gbps · direction=more
- 2026-07-03 · distance from GPU
memory can sit up to 20mm away
tags: 好数字·好观点 · → daily
value: qty=20mm
- 2026-07-03 · substrate layer count required
SPHBM4 will force the use of premium, high-density ABF substrates packed with 20 to 28+ layers
tags: 好数字·好观点 · → daily
value: qty=20 to 28+ layers · direction=more
- 2026-06-24 · addresses packaging bottleneck
SPHBM4 (Standard Package HBM4) tends to get read as faster memory because of the "HBM" in the name, but the real weight sits on the "Standard Package" half: it's about mounting memory onto a cheap standard substrate instead of an expensive silicon interposer, which makes it a standard that addresses packaging, not memory performance.

- 2026-06-21 · 无需先进封装
The big advances would be that there is no need for advanced packaging of HBM with gpu

预测 (forecast) (1)
- 2026-06-21 · 带宽目标
That would give 2.2TBps
tags: 好数字 · → daily
value: qty=2.2 TBps
事实 (fact) (4)
- 2026-06-21 · 目标信号速度
SPHBM4 targets a fourfold increase in signal speed versus HBM4
tags: 好数字·好信源 · → daily
value: qty=44 Gbps · direction=四倍于 HBM4
- 2026-06-21 · 目标信号引脚数
thereby cutting the required signal pin count to roughly one fifth
