[Concept] Project A100 Series: 20W Single-Slot Efficiency Solution for SFF Platforms

[AandM_sffuser]

Hello Intel Community and Engineering Teams,

I am a hardware designer based in Poland, inspired by the R&D work happening at the Intel Gdańsk campus. I am writing to share a reference design concept for a high-efficiency, ultra-compact GPU solution based on the Intel Arc architecture: The B100 Series.

The Problem:
The current Small Form Factor (SFF) market, particularly for recycled office workstations (OptiPlex, Elitedesk), lacks modern, single-slot, low-profile GPU options that stay within a strictly efficient power envelope without sacrificing cooling longevity.

The Solution: B100 Series "Sentinel"
The "Sentinel" is a conceptual study for a 20W-28W TBP card designed to provide modern AV1 encoding and 1080p utility in a true single-slot form factor.

Key Technical Specifications:

Target Power: 20-28W TBP (optimized for systems with limited PSU overhead).

Form Factor: Single slot, Low Profile (true 16mm width).

Cooling Architecture: "Copper Hybrid Skeleton" – Utilizing a solid copper core for immediate heat soak from the die, paired with high-surface-area aluminum fins.

Thermal Management: Optimized for low-RPM 40mm fan curves to ensure silent operation in office environments.

Connectivity: DisplayPort 2.0 / HDMI 2.1 (optimized for 4K/60 productivity).

To maximize the 20-28W envelope, Project B100 Series proposes an evolved DeepLink 2.0. This would allow any B100 card to 'Join Forces' with the existing Intel UHD/Iris Xᵉ iGPU found in most SFF platforms. By offloading basic texture rendering (in 3D shader-heavy games), Windows desktop or XeSS calculations to the iGPU, the total system efficiency increases without increasing the dGPU's thermal footprint.

Target Technical Specifications:

Arc B110
Xe2 cores: 3
VRAM: 4GB GDDR6 + 512MB (256MB / 2) buffer for iGPU
Memory bus: 64-bit
Clock target: 800MHz base, 1250MHz turbo
Special feature: AV1 codec support, DeepLink 2.0 (proposed), legacy BAR optimization for iGPU buffer VRAM
TBP: 20W

Arc B120
Xe2 cores: 3
VRAM: 4GB GDDR6 + 512MB iGPU buffer (256MB / 2)
Memory bus: 64-bit
Clock target: 852MHz base 1301MHz turbo
Special features: same as Arc B110
TBP: 20W

Arc B130
Xe2 cores: 4
VRAM: 4GB + 512MB iGPU buffer (256MB / 2)
Memory bus: 64-bit
Clock target: 825MHz base 1275MHz turbo
Special features same as B110 + dedicated fan for cooling + custom fan curve
TBP: 28W

Arc B140
Xe2 cores: 4
VRAM: 4GB + 512MB iGPU buffer
Memory bus: 64-bit
Clock target: 880MHz base 1330MHz turbo
Special features: same as B130
TBP: 28W

Design Vision:
This design is intended to be highly scalable. While the B100 Series focuses on the entry-level segment, the "Copper Hybrid" architecture is designed to scale toward the upcoming Battlemage (Xe2) B380 series, potentially allowing for 45W performance in the same physical footprint.

I am sharing the attached renders and thermal logic for community feedback and for evaluation by AIB partners (Sparkle, ASRock, etc.) who are looking to lead the "Efficiency First" movement in the SFF space.

I look forward to discussing the technical feasibility of this cooling solution with the community.
